I love the beer list. I usually go to the Metropolis location, but Decatur's has more flavored beers to choose from and more overall, and in my opinion has a better decorated interior. Also it's a five minute walk from my apartment, which is nice, because their tiny lot fills up very quickly and I frequently don't carry enough change for metered spaces.
I love their queso dip, fajitas, Peachtree hills chicken, and burgers. Most of the food menu doesn't appeal to me though.
And I love getting the beer of the month on Thursdays with a free pint glass!
Pros: beer list, quick service, super close to me
Cons: limited parking, menu not really to my taste
