They have cards at guest services listing all the gluten free places. Sounds good, until you look at the card. All of the places are on the club level, which you can't get in to unless you have a club level ticket. Freaking brilliant.
Although some might disagree, one cannot live on gf beer alone. Nor does everyone sit on the club level. In desperate need of a gluten-free only concession stand, like Coors Field has.
