We stopped by yesterday afternoon after watching the World Cup match at Movida and found ourselves across the street from Tap and Still. It was quite interesting watching the very friendly servers trying to adhere to what seems a bit cumbersome practice of ordering and serving as explained by the OP. There seemed to be quite a long wait for food, but the gentleman sitting next to me was back the second day in a row as he enjoyed it so much. I think they may have to figure out a way to get the food delivered more quickly as quite a few "bags" were left on the pass for some time. The whole thing just seemed awkward.

All in all, we enjoyed a simple patty melt, the meat was quite flavorful and the bread wasn't mushy as I thought it might be after being in foil and bag. The $4 beers and forced 20 % tip left hubby shaking his head. Not sure if we will return.
