The Amherst Brewing Company serves up many common "brewing company" foods - great appetizers, sandwiches, pub grub, a few steak selections. I think they're the best at their burgers, which come in lots of varieties - first you get to choose a beef burger, grilled chicken, or portabello mushroom. Then you can pick toppings or seasonings. Examples: Grilled chicken with avocado, cajun-blacked beef burger with jalapenos and salsa. The best thing about ordering burgers is that you get to choose what type of fries you want - regular or sweet-potatoes. I don't know where else you can sweet-potato fries in New England. If you've never had them, give 'em a try.
I've never had a problem with the waistaff, though the bartenders could be a little more friendly.
