Anyone with serious food allergies should always ask the server about problem ingredients. I know that one of the pasta dishes has shellfish. However, there are also other alternatives on the menu. I have discussed with them better identification of gluten free items and to have gluten free buns available for the smash burgers. They could also be served without a bun in a lettuce wrap. As I have talked with WHG, I believe that they will consider requests to leave out ingredients if they can or to do a substitute ingredient if possible. I believe that the Yorktown Grill will be sensitive to the issue and do their best to accommodate within reason. However, in the end it is up to the individual to ask and to request an accommodation.
I am not sure what you mean by providing support or accommodations for residents with food allergies. My belief is that they will do what any good restaurant in the community would do if asked. Will they have a special gluten free kitchen where no cross contamination is possible? I would say to that the answer would be no.
