Fries are unsafe because of a shared fryer, but burgers on a GF bun are safe! They recently updated the app and either removed the ability to mark allergies or made it really hard to find, so be careful when ordering with others getting gluten-containing buns.
Staff seems to be well trained or understanding about cross-contamination. I made an online order and they put my gf burger in the same container as my girlfriend’s (a regular burger), and they were touching. When we told them about the issue and that I am celiac, they remade the burger for free, and gave us free ice cream for the trouble.
Good food, good people.
Fries are not safe, but the gluten free bun is prepared separately and pretty decent. Yummy burgers! They put in an allergy order. Staff was knowledgeable and avoided cross-contact well. Shacksauce is unfortunately not gluten free either. Limited options, but a good burger!
Most Shake Shack locations offer gluten-free buns for burgers. A lettuce wrap is also an option.
