This place is great! The reviews on Yelp are accurate, good food, nice ambience and amazing selection of beers, including Omission gluten free lager and ale!
They have a "gluten sensitive" menu, which is unusual, in that it's a version of their regular menu but with instructions on what you need to REMOVE from your order to get it gluten-free. However, they are at pains to point out that their kitchen is not a gluten free environment, so it may still not be suitable if you're celiac.
I'd definitely go back, but be warned we went mid-week and it was BUSY!
