I purchased a yellow gluten-free cake with chocolate frosting from Barton's for my Aunt and Uncle's anniversary. (Gluten-free is better for your health, btw.)
I was just glad to find one that was gluten-free, and hoped for the best. To my surprise, it was the best cake I have ever eaten. Everyone who had a piece agreed.
Even if you aren't gluten-free, get the gluten-free option anyway. It is fantastic. I don't live in the area, and depended on yelp ratings to find the best.
That's why I bothered to come back on to give a rating. Seriously five stars.
