San Francisco is a foodie city with more than enough restaurants to satisfy any craving. The last few times I've made reservations at places that usually require them, I've looked around thinking that I didn't need to bother calling ahead. The one exception was when I dined at the Italian restaurant that changed its pricing scheme [1] to offer cheaper portions of the same quality dishes. Have you noticed that restaurants aren't as busy they used to be?
