Check the MLB website for latest GF info. I had read a review from a year ago, which stated that the York Market had GF options. They didn’t have much - just salads and fries - but there were lots of other options in different locations in the stadium. I didn’t get sick from anything and the staff seemed knowledgeable about celiac/GF foods. I was disappointed to miss out on GF chicken nuggets but didn’t want to take the time to go to a different section. They did have the glutenberg beer in the King section, which was good.
