I was worried we were going to show up and have to wait for brunch on Sunday, but that wasn't the scenario at all since I don't think that many people know it is open! When we arrived we were the only ones on the bar side and were sat right away.
There wasn't a brunch menu, but we were told since they were only open for 3 days (at that time) that there will be one made up in a couple weeks, along with another more extensive menu.
They had a drink special which was a $6 flight, but no food specials.
Both of us were in the mood for breakfast so we ordered the croque madam. It was AMAZING, I'd go back pretty much any time of day to have another one.
The service was excellent and the space is really cool. I cannot wait to go back and try more food, beer and just test the atmosphere.
UPDATE: Came back to try more... They were all out of every IPA (which was really lame for a tap house) Tried more of the food (wings, layer dip, calamari - stay away from this one, it was fishy, rubbery and overall not good) the staff were still very accommodating but I had to lower my stars for the beer experience.
