I ate lunch at Curry In A Hurry located in the Morgan Street Food Hall. They offer 4 Indian curries which are all gluten free served over basmati rice. I had the butter chicken and it was very good! They also have green curry chicken, lamb curry, and Channa Masala (vegan).
As for other booths, there is a place for macarons, GF empanadas (I believe they offer frozen, take-home empanadas by the dozen), lobster bisque and clam chowder, and burgers and fries. Please note that I have not tried any of these options!
