Traveling with a friend to NYC later this month. She will be celebrating her birthday while there. We have a reservation at Babbo for dinner. Need some ideas where to go afterward. The catch is,I'm 48,& the birthday girl is 33. Are there any bars or clubs we can go to where I wont feel like everyone's mother? I'm not the hippest person in the world,but I'm not dull either. Any part of Manhattan is fine.
