I have celiac so ordered a burger without the bun and salad instead of fries (just in case of cross contamination) No issues and everything came out as ordered. Not a whole lot of options but if you’re ok with a burger and salad then highly recommend.
Very little for gluten free options especially if cross contamination is a concern for you. Burgers without a bun and without fries (boring) or lettuce with grilled chicken or smoked trout is pretty much it. There are MUCH better option in the area, many have dedicated gluten free choices, not just menu items where you have to take half of the ingredients away to make it gluten free as you do with this place.
This is an extraordinarily hip bistro in Greenpoint, so it is crowded and the music is loud (although not offensive to my 67 year old ears!), and the food is somewhat expensive. There is no GF menu, no GF bread or pasta, but they are "hip" to gluten. My family of 3 celiacs has been 3 times and never sick. We trust the waitstaff to advise about safe menu options and have had wonderful meals. Worth the hassle for a very special GF meal.
