I'm hanging around Moscone Center the next few days for work. So far, I've had dinner in the Westfield basement food court, which was edible, to put it nicely. But La Boulange was nice for lunch today, and based on cursory research I might stop by Cafe Madeleine tomorrow for something similar. In the evening I might do Ryoko's, Kare-Ken. Zuni Cafe is enticing, not in the least for foodie reasons, but it's much farther to walk, so I'll save it till the weekend. Aside from these, if there's a place nearby that's considered must-try I'd love to know of it.
The other possibility is eating out of Whole Foods Market; the options are healthier, which I do prefer. So if there are places to obtain decent servings of vegetables and lean proteins, I would really appreciate that as well.
