In addition to the PBR and Narragansett, they serve Arch Amber Ale, a good strong beer.
While I wouldn't pay three bucks for a few big fries, I enjoyed their organic chili cheese fries. For just about $5, they're a good lunch in themselves: the delicious potatoes are a solid foundation, the absolutely unique chili pulls none of its sharp, sweet punches, a perfectly savory cheese sauce rounds it all out, and the guy behind the line is happy to throw a couple slices of jalapeno on top.
My other fast favorite was their "Ultra Burger" - caramelized onions, mushrooms, and that cheese sauce over one of their burgers. I like the burgers, by the way. Nicely seasoned.
