Went with some friends to my first Yankee game and was so excited to see that they had gluten free hot dogs and sausages with a gluten free bun! The cart is no longer labeled as gluten free sadly but it’s called NY GRILL and it’s right in front when you walk in the Gate 6 entrance. The buns are Udi’s I believe and a little hard but was glad that at least I could enjoy a hot dog! After having been to both, I would say if you have no loyalties to a certain team, CitiField has a bit better gluten free food than Yankee stadium (chicken tenders, pastrami sandwich, hot dogs, sausages, etc), but still so nice to see options at both!
