I lived there for the past 15 months, and I'm sorry to inform you, it is not very exciting. Things close fairly early, there are no bagel places, no Chinese food (short of a P.F. Chang's type place-> AkA expensive), no deli's, and awful pizza if you can even find something other than a Domino's or a Little Caesar's. If you want to go out to dinner at 9:30-10PM on a Friday, it's barely possible, short of like two places that I know of and a handful others. There are also no diners.
Aside from food, the weather is actually quite nice and it's relatively cheap to live there. If you don't have a car though, you'll be in bad shape and pretty much limited to the public bus transportation system. There are no trains or subways. University Way is the "college street" and everyone calls it "The Ave" and is something similar to say Thayer Street in RI or Comm Ave in Boston... however there are far less people doing stuff there and it also closes early. We went there on a Saturday night and it was compeltely dead. We actually asked random people where all the college students or people went, because it seemed almost deserted, despite the many bars that are there.
The Magic scene in Seattle is complete GARBAGE. Despite the fact that there are three prominent online stores located relatively close to each other (MagicArsenal.com, Cardhaus Games, and CardKingdom), there are few players, no shops to really play, and the ones that do play are rather different than most of the players I've been fortunate to meet on the East coast. The Type 1 scene is non-existent, short of a monthly tournament at Mirkwood, which I hear is a really awesome place, but about 45 minutes from Seattle or so. If you're lucky, you'll get some awesome Canadians from BC to show up, most notably Foolish Mortal and his crew who are all awesome guys.
