I get at least one meal from San Juan Island Brewing Co when I’m in Friday Harbor. Their gluten free offerings are limited, but they do have GF buns and a range of salads. I’ve found the wait staff knowledgeable and happy to check on ingredients. I’m allergic to wheat but have not had a reaction to their food.
Most of the pizzas and sandwiches can be done gluten-free. They put the pizza on a separate pan, and it goes in the big oven with the rest - be sure to inform them of your allergy, as it felt high-volume. Once the staff understood, they were careful. Limited cider/wine selections - but hey, it's a brewery!
They have two ciders, some wines, and a GF beer at the moment, but the waiter informed me that my only food options were the salads or the poke without wontons. (Note that the menu offers “GF” pizza crust and burger buns, but neither is celiac safe.) I had a really great cider and got lunch at the grocery store in town.
This brewery first opened in Summer 2017. Apparently the owner aims to have GF offerings that are safe for celiacs; the waitress told us they have a different prep area for the gluten free burgers and pizzas— they have “a system”. The GF crust was very thin and tasty, prepared off-site. Also hard ciders on tap and GF buns for burgers. Unfortunately no dedicated fryer so the fries are not GF. Good food, and a good experience!
