Although there are tables and chairs on the first floor, what I suggest is that we follow the signs that say "MarketBar" up to the 2nd floor. One must, in fact go up two full flights of stairs to get to the second floor, so one might think that it is the 3rd floor, but there is also a mezzanine.
There are stairs and an elevator near the entrance off of 1st street.
Look for me and my "meetup.com" sign.
