686 Bar

If you’re having dinner at Em, your next move should be a martini upstairs at 686 Bar. Waiters wear crisp white jackets, and there’s a bit of a 1950s energy to the very dark, moody, incense-heavy space. And while it doesn’t attempt to be a proper restaurant, they do make an extraordinary burger, which might be a good idea for a second dinner after you’ve had two or three of those martinis. Reservations are definitely recommended, so make one of those in advance.
