Ordered off their gluten free menu and informed the staff I had celiac disease but got glutened.
UPDATE:
I had family in town who wanted to try Nitty Gritty so I decided to give it a second try. Despite letting them know I'm celiac and needed my meal gluten free I got sick again. I'm writing this place off permanently as not safe, I'm sensitive to small amounts of cross contact but anyone with celiac should be wary.
They have a gluten free menu which lists the options and which of those need to be modified to be gluten free. They can give you an excellent gluten free bun with any of their gf burgers or sandwiches. I go there frequently and get the grilled salmon sandwich. I have gotten their fries (dedicated fryer) in the past, but the sandwich alone is a lot of food so now I get the sandwich without a side. I think there is a beverage or two that is gluten free, but I have never ordered one, so I am not sure. I keep getting curbside takeout, so I cannot speak to their cc measures.
I am not sensitive.
