I work in Lower Queen Anne and sometimes have the urge/need to go for a long-ish lunch. Tomorrow will probably be one of those days, so this is where you come in.
I'm familiar with most of the offerings of Upper and Lower Queen Anne. Belltown and South Lake Union, on the other hand, are within walking distance of my office but hold many places I've yet to try. Pike Place has proven to be too far for lunch, even for relatively quick places like Il Corvo and El Puerco Lloron.
Restaurants I have visited for lunch in Belltown: Boat Street Kitchen (good sandwiches, but the entrees have been more miss than hit lately), Bambino's (worth it even if you can't drink during the day), Tilikum Place Cafe (excellent, probably the best in this list), Local 360 (not bad, but lunch service feels like an afterthought), Barracuda Taqueria (maybe my least favorite taqueria experience in the city)
Restaurants I have visited for lunch in South lake Union: Re:Public (despite the dinner menu's ambition, the lunch menu is really boring), Serious Pie, Dahlia Workshop (as delicious as it is unhealthy)
What else is out there? Is Ting Momo worth visiting yet?
