When we were there, we got there around 3:50pm and were given a pager that would buzz once they were open. We got buzzed at the same time folks who got there at 3:30 (or earlier) did, so we basically all piled in together. The place ended up being full once we all were seated, but we did get a seat at the bar. Worst case, you could always sit on the patio - ample seating out there.
