I have had worse burgers for $20, but this was far from the best I've had as well. Our food was well prepared, came out cooked Medium as ordered, and was tasty without being memorable. The helpings were big enough to fill me, and overfill my wife. They have an extensive craft beer selection, and I thoroughly enjoyed my choice - my wife likewise enjoyed her (amazing looking) milkshake. I was dissappointed not to be hungry enough to follow my burger with a desert shake for myself, but that will have to wait for next time.
The service was decent, I don't have any specific complaints, menu was comprehensive without being extensive, and seating was comfortable, if just barely.
This won't be the top of my list for a return trip, but is solid enough that I'd probably eat here again.
