Best locker room: David Barton Gym

You’ll want to work out daily just to have access to the Bumble and bumble hair-care products in the showers. (We’re not ashamed to admit we’ve visited this gym for a sans-workout rinse a few times.) But before we hit the shower, we always make time for a steam and sauna; they’re the best (read: biggest) we’ve seen at any gym in the city. Did we mention the gorgeous dark wood lockers and benches? We’ll take one of each to decorate our home.
