The Livermore is fucking great. Certainly gets packed on the busy nights, but that's what I want on a Friday. Weekdays are much more relaxed, and it's an awesome place to meet someone for conversation. The food is killer, lots of rich and salty food to go with awesome cocktails. Don't stick to stuff you're comfortable with, talk to the Bartenders, they're super cool. Tell them what you like and they'll pretty much always make you something you've not had before that you're gonna want again.
Plus, if you don't wanna spend a bunch, there's always their 3 dollar beers, which is pretty nifty in a space like that.
