As previously stated, about 9 is when you can expect it to start getting dark.
There is an Elliott's Oyster House right on the waterfront downtown too - great views, outrageously good food (all seafood, not just oysters), and much, MUCH less expensive than Anthony's, unless you go to the downstairs "cafe" at Anthony's, which is the same food more or less, but more affordable.
Best Mexican Food - Tia Lu's in Belltown, The Chili Pepper in Freemont
Best Greasy Spoon - The Hurricane downtown or Beth's on Aurora
Best Burgers - Blue Moon Burger in South Lake Union, Redmill in Queen Anne, The Counter in Ballard
Best Thai - Jamjurri, Romai Thai, and Samui... all on Capitol Hill
Lived here my whole life
