Sunday afternoon at Battery Park Book Exchange is already a vibe with the books and bubbly, and Parker's Back is playing at 3pm. Good way to ease into the end of the weekend without committing to a late night. The door policy gets a little stricter on weekends, word is they're checking IDs and keeping it 21-plus Friday through Sunday, though younger folks can still catch the Thursday shows if they're supervised. It's all first come first seated across those two floors of couches and leather chairs, so if you're planning to post up with a glass of champagne during prime time, get there early.
