I called Barbette to check and they Do NOT have a dedicated fryer. The person who answered the phone had to check with the kitchen before answering.
Dedicated fryer for their great french fries! A lot of the entrees were also GF, and for dessert there was creme brûlée that was GF. However the waitress wasn’t really knowledgeable and I needed to explain gluten free to her a bit and she needed to ask the kitchen things before she could help me navigate the menu.
