Wooooooooooooooo! Fellow Seattle-ites! Soooo excited! Hope you stick around!! There are several of us here!! Maybe we should even get together for dinner! (OK, I don't do that so much, but I know others here have, or do...)
There are literally DOZENS AND DOZENS of great places in Seattle that are either vegetarian or even all vegan! What sorts of food so you like?
My friend Tofu-N-Sprouts (who used to post here) knows even better resources than I do, I'll see if I can convince her to come back here for a post or two, she knows veggie Seattle (and Tacoma, Bellevue, etc, etc) really really well!
