The best happy hours in Silicon Valley provide much more in the way of sustenance and ambiance. When researching restaurants, bars and wine shops for this piece, I kept in mind a few things. The first was, how much am I willing to spend at a happy hour? I went to places where I could spend $25 and only get one appetizer and one cocktail, but that didn’t seem like much of a bargain. I wanted to top out at about $20 for some high-quality food and inspired libations. The second thing was, how many people could be fed with those $20?
