I haven't played there in a while, but if I'm remembering correctly, unless they have other things going on or you want to use the Tolkien room, you shouldn't have to. Definitely call to double check, they'll be able to tell you for sure and let you know when things are going on. Also, they do have D&D nights, I think on Saturdays, where you can play with friends and make new friends as you play. And it's only $3 to get in.
Alexi got it (thanks!) There are almost always tables available, but you should check if you care how busy (loud) it's going to be.
