It's all about the name.
I ate at the Cheers at Faneuil Hall on May 16th around 6PM. It was a cool and rainy evening and there were plenty of open seats. I ordered the Honey BBQ Chicken Sandwich. While waiting, I ordered the Chips and Salsa (for the value, it was great!) When my sandwich arrived, I was extremely disappointed. The Chicken had about a quarter size drop of the Honey BBQ Sauce and about 10 small French fries. The plate was about $13 for a small amount of food. I was glad that I had the chips and salsa or I would have left hungry. The upside, if you eat there, you can get the nice Cheers beer mug for $5 instead of the $10 retail if you don't dine.
Service was quick. Staff was friendly.
If you want to say you ate at Cheers, be prepared to be slightly disappointed with the food.
