This city is full of hidden treasures, and Gallow Green, the verdant rooftop bar above Sleep No More’s McKittrick Hotel, is a charming surprise. In line with the theatricality of the show, a mysterious elevator ride deposits you in a staged secret garden that not only adapts to the seasons, but leans into them. Lush in the warmer months with greenery-lined walkways, plus musical entertainment and a menu offering salads and pizza, the space is transformed in the winter into a rustic lodge with hidden rooms housing cozy, flannel-lined bunk beds, and multiple nooks and crannies to get lost in. The outdoor area is not off-limits in the cold; blazing fire pits warm you up along with specialty cocktails like the mulled cider, Jack Daniel’s, and sherry Sleep No More — served individually or in samovars for group revelry. Reservations are recommended, especially if you’re headed to weekend brunch.
