If you're going to the Jaguars game tonight, you should be able to find Redbridge gluten-free beer in the Bud Zone.
At least the Jaguars intend to offer it, but actually finding gluten-free beer in EverBank Field has been a constant battle. I won't rehash all my past problems trying to find it, but suffice it to say it has never been easy to find. In fact, the bartenders who supposedly have gluten-free beer stocked in the refrigerator cases in front of them often don't even know it's there.
I'm not going to the game myself, so I won't be able to tell you if it actually is available.
Beyond beer, the gluten-free offerings at EverBank Field will be basically the same as last year, which is disappointing. You can get a hot dog with a gluten-free bun at the regular hot dog stands, but I wouldn't recommend it because I honestly don't have faith that the people working the concession stands know what they're doing.
If you're hungry, a safer bet will be the packaged snacks you can find at the Daily's stand.
The good news is the Jaguars say they are likely to have a separate gluten-free cart next season, as part of an overall revamp of their concessions. But for this season, you'll need to think about eating before you go in the stadium.
