I've never tried their magic shows or laser tag, but as for the arcade, Illusionz is one of those rare places that encourages players to socialize and enjoy themselves, besides just throwing money into machines. In addition to the aforementioned attractions, there's mini golf, batting cages, and a rock-climbing sim. Oh, and the food is really good (about what you'd expect for good pub food). Skip Gameworks -- this place has it beat hands-down; the machines are maintained better, there's a better variety, and the atmosphere is friendlier.
It may be far away from downtown Seattle, but it's definitely worth the haul.
Pros: Lots of good games, Clean/smoke-free, Well-maintained
Cons: It's in Issaquah, Closes early
