The above mentioned are very good.
I would add One Market to the list, it's very busy and as a result the service can be slow sometimes but the food is very good especially the salads and the fish is always nicely prepared. The seating is very comfortable and the tables by the windows are extra nice.
Ozumo - Japanese, good food, beautiful interior with views. A great place to have a business meeting. The service is so so but the food and atmosphere makes up for it. They are opening a restaurant downtown Oakland soon.
Rubicon- Is one of my favorites, all around the perfect lunch spot.
Aqua- I know it gets bad reviews from time to time but I had a recent lunch experience that was excellent.
Second the vote for Kokkari and Perbacco.
Also, tablehopper just wrote up a new place in the hood that sounds great, A new spot down the street:
The Italian-fest continues: just across from the Transamerica Building, the old Elisabeth Daniel/Tartare space reopened this week as ~CHIAROSCURO~, an Italian restaurant and lounge from Roman import Roberto Scaccia. Lunch is served Mon-Fri 11am-3pm, and dinner is Sun-Thu 5pm-10:30pm, and Fri-Sat 5pm-11:30pm. 550 Washington St. at Sansome St., 415-362-6012.
Stopped into Chiaroscuro to pick up menus and saw some colleagues eating. At the risk of getting the "hearsay!" objection, I'll simply say that my colleagues were quite disappointed with their food and thought much of it bland. But what I noticed was the noise level. The place is all hard surfaces, and although literally only two tables were occupied, every tiny sound was so magnified that I could not have a conversation with my colleagues comfortably. I can imagine how unpleasant it would be if crowded.
I'm eager to hear other reports.
