I'm gluten intolerant (so this place might not be a place for celiacs) but I didn't get sick.
They don't offer a lot of gluten free treats, I believe there is usually 3 options. I went during 4th of July weekend, so they had rice krispie, lemon- raspberry cupcake (delicious), "pop tart" . The pop tart is basically a cake square covered with jam and topped with icing Their pastries don't have that commercialized sweetness like Georgetown cupcakes/generic grocery store cupcakes do.
This bakery is usually crowded but that doesn't affect good service. I really enjoyed my sweet treats and plan to go back there again.
I recommend calling to see what kind of gluten free treats they have available.
