Gluten-Free Hot Dogs and Beer at Citi Field
Leaving aside new offerings like crab-cake sandwiches, Peking-duck buns, and lasagna Bolognese, it looks like the only real addition to Citi Field’s food-vendor lineup this year is a Kozy Shack Gluten-Free Stand selling “Kozy Shack puddings, hot dogs, hamburgers, sausages and beer.”

It's enough to make me want to go to a Mets game! I hope this is a trend that catches on... (that's supposed to be a pun). Let me know if you find any other gf offerings in unexpected places.
