Fun small venue. There's a full bar, but no food. No seats, unless you crab a table, otherwise it's standing/dancing kind of place. We had a "meet and greet package," which meant we got to enter earlier (at 5:30, whereas the concert was starting at 8:30). Since the place has "absolutely no re-entry" we had to spend some time inside: on the plus side, we were there through the sound check for Sirsly, on the down side, we got quite hungry and tired. There is a smoking area though, which smokers got to enjoy while waiting for the concert to begin. There are also spacious and clean restrooms, a bit old-looking but well taken care of. There is parking ($10 per car), and it didn't look too crowded.

P.S. Foodwise, there is a gastropub WURSTHAUS at Observatory, where one can get beer, sausages and fries, but it is a separate space:

"Pre-show reservation allows for early entry into the venue as well as free parking in our parking lot. Each guest in your party must meet a $15 minimum spend. No need to make a reservation if you're arriving after doors."
