I have left a review with very high marks for 12 Bones before, and stand by that - I have celiac and I love it.
I just want to jump back on to say that I learned from the chef that the mustard sauce contains small amounts of gluten. Previously I was under the impression of "all meats and sauces gluten-free," but it seems not so in the case of the mustard sauce. Just FYI.
— Somewhat
— Gluten-free items are marked on the main menu
— Some
— Excellent
