Found the craft beer location by Section 112. GF hot dogs....can't remember the last time I had one of those at a ball game! Omission beer and ciders to wash it down. Always limited GF selections at sporting events, but I appreciate the Giants accommodating my needs.
There is a new gluten free option at AT&T park called Hearth Table - located in dead center field under the stands in the new garden area. It has gluten-free flatbreads (in flavors like roasted red pepper, olive, and feta) it has a sausage flatbread too. They also serve a salad and a hot dog (although I'd skip the dog and go for the one near home plate as it seems better there for some reason). Also wine and 2 GF beers (one is Omission (some consider not celiac safe as it is merely"crafted to remove gluten") but the other is a true GF beer and isn't bad). Overall very happy to have these choices. Beautiful setting too. Doesn't seem to be any risk of contamination as entire stand is GF.
My son had the gluten free hot dog. Right where the previous poster said. Section 112. Budweiser stand. It looks like it's only beer but they have GF dogs. $8 which is not bad since regular burgers are $7. My son devoured it in 2 min.
Budweiser brew pub at promenade section 112.Sells gluten-free hot dogs and Omission beer.My son and I love this option! Head across the hall for the kids $5 Safeway meal and put your gf hot dog in the bucket. Yum!
