I used to game at Great Escape and play D&D and/or Mechwarrior DA there. It's not hard on the weekends to find a game table. I think Wednesday's they have Whorewammer tournaments though. Saturday's are pretty easy to get set up though. We never needed a reserve and we usually had a table capable of accomodating 8 people or so without a problem. The easiest way to assure this is to get there around noon when the store opens though. The later in the afternoon it gets, the more packed it gets. The best table for roleplaying is in the back, behind a wall. Helps cut down on the noise and everything from the Whorewammer players shouting constantly.
