My wife and I will be in SF this April, staying at the "W" Hotel in SOMA. What do you recommend for good places to eat lunch within a 10-15 minute walk from there? They don't need to be fancy or high-faluting (in fact, we'd like it better if they weren't). We're doing Vietnamese and sushi for our 2 dinners while we're there, so something different than that would be good. "Get-down" Italian, Indian, seafood, great sandwiches, or anything else. We just don't want to take our lives in our hands getting there and back. Thanks!
