Cezanne
Open Friday and Saturday only, this tiny wood-paneled loft above the Black Labrador restaurant features jazz meant to be listened to and appreciated, not talked over. Plus, with only 40 seats, you'll probably get some death stares from the local and national musicians that play here should your attention be less than rapt. This classy joint is great for martinis and impressing your date.
You'll want to make sure and eat beforehand, since the focus is on the music and drinks are only meant to amplify your listening pleasure. This spot often welcomes the most critically acclaimed national jazz acts for a small cover fee, so check the events calendar often.
