When I visited Pink Baking Co. there were 3 gluten-free cupcake flavors to choose from: chocolate, salted caramel, and peanut butter. I limited myself to 2 and got the salted caramel and peanut butter, both of which were delicious. Both had a moist chocolate cake with a generous delectable frosted top.
The service was great and atmosphere inviting. They also offer wine and beer (I didn't notice a gf beer option) which I'll have to take advantage of on my next visit.
I don't know whether or not this establishment is celiac friendly.
