Jack London Square -Other than Yoshi's
There's Silk Road at the end of Broadway accross from Chicken and Waffles. There's also Ginza another Japanese joint 2 doors down from Nations. There's a Mexican place next to Nations as well. Never been, but there's also a Peruvian place diagonally across from Nations too.
Soizic Bistro -- nice, upscale, dinner
Jack's Bristo -- nothing special, cal-med, but nothing bad either
Everett and Jones Barbecue -- you'll hear the good and the bad like all bbq
Chicken and Waffles -- a knock off of Roscoe's in LA, good, on the low end
Oakland Grill -- breakfast and brunch good
I'm a big fan of The Fat Lady - I've been there half a dozen times over the last couple of years - last time about six months ago. Neither I, nor my dining partners have been disappointed. It's got a funky decor - psuedo New Orleans, they claim its 'Victorian'- but the food is quite good. It's a typical California style steak/seafood kind of place. Ceasar salad, bruschetta, goat cheese salad are all great appetizers and the steak and seafood entrees are always solid. The burger is quite tasty - nice juicy and they'll cook it rare if you ask 'em!
Oh, and the best part - they very much disdain cell phone usage. My kinda place.
It's a little off Jack London Square on Washington St. About a block away from the large parking structure adjacent to Yoshi's.
