I assume you're talking about Super Smash Games. I actually made it out there last week. It's $3 entry to sit in the back of the store playing smash, they have a bunch of CRTs so you just have to bring your console if you want your own setup. I think they might do brackets sometimes. They do this Tuesdays 4pm-10pm.
Also, you should check out Gameclucks in Lynnwood on the first Saturday of every month(barring the 1st day of the month). You probably know about it already, but it might be worth the monthly trip. There isn't one this month though, it's cancelled for NW majors.
