EMP Summer House will be the official outpost while the restaurant’s dining room and kitchen are under renovations, taking over for the old restaurant space occupied by Moby’s on Pantigo Road. If you’re looking to snag one of this summer’s hottest tables, have your AMEX handy— EMP Summer House is only taking reservations from American Express cardholders, starting May 1st. Those without AMEX cards can try for available walk-up spots when the restaurant is open, which will be cash only.
