Fast food runs on a simple bargain. Speed, a price you do not have to think about, and a product that resembles the picture on the menu board. The American Customer Satisfaction Index has measured whether chains hold up their end since 1994, and its 2026 restaurant study was built on 16,464 surveys collected by email between April 2025 and March 2026. Quick-service restaurants averaged 79 out of 100 for the third year running. One chain landed at 72, tied with Dairy Queen for the lowest score of any quick-service brand measured. It is also the most visited fast food brand on the planet, with 45,356 stores worldwide as of 2025. McDonald’s.
Below, ten chains, from the ones leaving customers coldest to the one doing it better than anybody in 2026.
10. McDonald’s
Scoring 72 in the 2026 index was actually an improvement, up from 70 the year before, and it still was not enough to get off the floor. McDonald’s finished last in 2023, last in 2024 and last in 2025. The distance between McDonald’s and the top-rated chain in 2026 is 12 points.
Price is the complaint that keeps surfacing, and the math behind it is not subtle. The average Big Mac cost $4.39 in 2019. An a la carte Big Mac now runs $8.59 in Sacramento, California, $6.29 in Columbus, Ohio, and $6.49 in Raleigh, North Carolina, an increase of as much as 96% against roughly 30% general inflation over the same stretch, as tracked through the Bureau of Labor Statistics inflation calculator.
The company disputes the idea that prices have doubled. In a 2024 open letter, McDonald’s USA president Joe Erlinger put the average menu increase since 2019 at about 40%, driven by costs including worker pay up as much as 40%. Chief executive Chris Kempczinski has said McDonald’s heard affordability concerns “loud and clear,” and the chain brought back Extra Value Meals, including an $8 Big Mac meal and a $5 Sausage McMuffin with Egg meal in September 2025, then promoted an $8 10-piece Chicken McNugget combo that November. Customers mostly replied that $8 for ten nuggets, a handful of fries and a drink is not a bargain. A $2.50 McDouble on the McValue menu drew the same reaction, with longtime customers pointing out the sandwich once sold for 99 cents.
Then there is the loyalty program, which used to be the reason to tolerate the rest. In May 2026 the chain raised most reward tiers by 500 to 1,000 points, so a Big Mac or 10-piece Chicken McNuggets now costs 7,000 points, up from 6,000. Members worldwide placed nearly $37 billion in orders through the program in 2025. Devaluing that many people’s points at once is a choice.
Traffic has not followed satisfaction, which is the whole paradox. YouGov’s 2026 Best Bites report found 39.6% of Americans would consider McDonald’s when choosing fast food, well clear of Chick-fil-A at 35.5% and Wendy’s at 33.2%. Ashley Brown, senior director at YouGov America, told Fox News Digital that McDonald’s “leads all fast-food brands in consideration when Americans are deciding where to purchase fast food, despite ranking behind several competitors on best-tasting burgers.” Being unavoidable is not the same as being good.
9. Dairy Queen
Dairy Queen matched McDonald’s at 72 in 2026 and sat at 72 the year before, which is a remarkable amount of standing still for a chain with more than 4,000 U.S. locations. YouGov finds 73% of Americans view it positively. The post-visit score says liking a brand and leaving it happy are not the same measurement. Blizzards and Dilly Bars built the identity, and seasonal Blizzard variations have not translated into customers leaving happier, particularly against competitors spending money on menus and remodels.
8. Popeyes
Popeyes slid to 73 in 2026, the lowest of any chicken brand in the index, down from 75 in 2025. That is a hard place to be in a category where Chick-fil-A, Raising Cane’s and Wingstop are all pulling in the other direction. The chicken sandwich that made Popeyes a cultural event in 2019 is still a good sandwich. It is no longer doing the heavy lifting it used to, and the rest of the experience is what the scores are measuring.
7. Little Caesars
A 77 on the 2025 index, and a 78 in 2026, flatter Little Caesars considerably. Its ratings on public review sites run low, and the grievance is almost always the same one: long waits. For a chain whose entire pitch is “Hot-N-Ready,” waiting is the one thing the business model is not supposed to allow, and the app that was meant to fix it draws complaints about overcharging and outright failing.
The pizza itself gets described as bland and doughy with striking consistency. That was survivable when it was the cheapest pizza in America by a wide margin. Prices crept up, the product did not improve, and the value argument stopped working.
6. Burger King
Burger King is the rare chain that has conceded the point. In February 2026 the company said it would redesign the Whopper experience with a new bun, creamier mayo and a clamshell box in place of the paper wrap, a response to complaints loud enough that ignoring them stopped being an option. The underlying problem was never just the recipe. A well-made Whopper is a genuinely good flame-grilled burger. Too many arrive cold, squashed and assembled carelessly, with no trace of the flame-grilled flavor that is supposed to be the entire reason you drove there.
The fries have long been considered among the weakest in the category. Burger King has also closed hundreds of underperforming U.S. restaurants since 2023, which puts more pressure on the stores still standing. The score was 77 in 2025 and 78 in 2026, tied for the best burger score in the index.
5. Sonic
Sonic bottomed out at 73 in 2025, one of the steeper falls that year, and drew a steady run of complaints about wrong orders, runny shakes, an app that fails and waits at the stalls that stretch past any reasonable definition of fast. Then it posted the largest single jump in the 2026 index, climbing to 77.
That is real movement, and it is worth saying so. It also starts from a low base. Sonic’s identity is drinks and the drive-in, and when customers report watered-down flavors and locations steering them to the drive-thru instead of the stalls, the brand is competing against its own nostalgia.
4. KFC
KFC took the single largest satisfaction drop of any chain in 2025, falling from 81 to 77. The complaints were specific rather than vague: smaller pieces, greasier and soggier batter, chicken that came out dry inside a thick crust, and prices that climbed without anything improving.
Pricing on tenders became its own running joke in 2026, with customers reporting nugget-sized pieces at figures that made no sense next to the competition. KFC fell to fifth among fast food chicken chains by consumer spending while Chick-fil-A, Popeyes, Raising Cane’s and Wingstop all grew in 2024.
Credit where it is owed: the 2026 score came back to 80, above the industry average of 79. Whatever KFC did after that collapse, customers noticed.
3. Subway
Subway spent years as a punchline and scored 76 in 2025, down in the territory where Chipotle and Five Guys were sitting. In 2026 it rose to 79. That is one of the better year-over-year recoveries in the whole survey, and it happened quietly while everyone was arguing about burger prices. The lesson Subway appears to have relearned is that a sandwich made in front of you, for a price you can predict before you order, is a durable product.
2. Chick-fil-A
Eleven consecutive years at the top of the index is not an accident of branding. Chick-fil-A scored 83 in 2025 and 83 again in 2026, holding steady while plenty of larger chains wobbled, and it does it while generating nearly $24 billion in sales from restaurants that close every Sunday. Order accuracy, staff courtesy and speed are the benchmarks the ACSI actually measures, and Chick-fil-A wins on the boring ones. The only reason it is not first this year is that somebody finally scored higher.
1. Jersey Mike’s
Jersey Mike’s posted an 84 in 2026 and took the top spot outright, ending Chick-fil-A’s eleven-year run and becoming the first chain in over a decade to do it. The win says something about what Americans are now willing to pay for. Not scale, not a drive-thru on every corner, not a loyalty app. A sandwich sliced to order, the same way, every time.
Forrest Morgeson, Associate Professor of Marketing at Michigan State University and Director of Research Emeritus at the ACSI, framed the shift this way: “Price still matters, but it’s no longer enough on its own. Consistency across the full experience is what separates the leaders right now, and that’s showing up clearly in the data.”
That is the verdict in one line. McDonald’s is cheaper to reach, faster to find and nearly impossible to avoid, and it has finished last, or tied for last, four years running because none of that is the same as being satisfied when you get back in the car. Twelve points separate the bottom from the top. Those twelve points are worth a short detour.
