Would you say it's primarily a donut chain, as opposed to a coffee chain? I took the lead from Quizmaster's Most Popular Fast Food Restaurants quiz which has it under Coffee.
Dunkin is definitely more known for coffee than donuts. That's why they changed their official name to DUNKIN and dropped the donuts. That said, loving all these quizzes.
91% of people clicked donuts, so at least based on this quiz I don't think I could say it's definitely more known for coffee. Though maybe that's just due to its history. Either way I think I'd get more complaints if I changed it to coffee.
Yeah seems people are maybe clicking burger, but they call themselves a sandwich shop as does wikipedia and other sources. The only mention of burgers on their wiki page is about them being an alternative to burgers.
I worked at Arby's in my teens (I'm now 50-something), and we were a roast beef sandwich shop. Arby's didn't start diversifying its menu until the early 00s, and I think Arby's started selling burgers only a couple of years ago.
Many of these places have multiple right answers. Clicking on the most common answer is easy enough... but Arby's also tripped me up. I guess technically they don't serve hamburgers. But... they have chicken burgers.. and everything else any other burger joint has... take out the hamburger patty and swap in some dry flavorless roast beef and it's basically a McDonald's clone.
