The Decade Diner near right field! The chef went and made me a gluten free cheese burger with an udi bun in another area so there was no cross contamination. They wrapped it up specially. I felt very comfortable eating there.
Only option (during a concert) after running on a wild goose chase with supposed options from Fan services ended up being what I found on my own. A bag of chips and a box of popcorn. Staff had no clue and was rude when asking questions. Fan Services people were nice but still gave no help after sending us to a dead end. Eat before you go.
They close the only GF place during concerts.
If you don't want to eat in a restaurant during the game, the only option is an all beef hot dog with no bun at Vienna Beef. Oh, and cracker jacks and popcorn. Really Wrigley? Have you looked at how much the Sox offer gf? Pretty much all other major league sports venues in Chicago have more than a plain hot dog zero bun available. Remind me next time to pack our own food. The $ I spent on 3 hot dogs, no bun could have gotten me two 8 packs of gf buns plus a pack of hot dogs.
The gluten free bun at the Decade Diner was great!
Only place in the park with a gf bun, had to walk a long way to get there but the bun was excellent
There is Redbridge available at various concession stands and a couple gluten-free snacks at the concession stand outside section 122.
