It's Friday. It's sunny. You deserve poolside drinks after work.

Mason & Rook Hotel, which opened in the former Hotel Helix near Logan Circle in late April, quietly unveiled its rooftop bar and lounge yesterday. While visitors can't take a dip – the pool is for hotel guests only – they can take in views of the city and soak up the sun on lounge chairs while sipping an Orange Crush or glass of rosé.

The short-and-sweet drink menu ($9-$11) is different than the list offered at the ground floor bar Radiator. The standout of the half-dozen drinks is a variation on an Orange Crush, made with local Jos. A. Magnus vodka, triple sec and fresh-squeezed orange juice. For something more tiki-ish, there's the sweet, rich Full Monte, with aged rum, pineapple juice, coconut crème and a bit of Amaro Montenegro. Seven wines ($8-$10) are available by the glass, including French and Californian rosés, and there's a selection of beer in cans. (Because of the pool, no glass is allowed on the roof.)

Unlike downstairs, the rooftop bar doesn't offer happy hour, but a hotel spokesperson says "it's something we might explore in the future."

The bar opens at 4 p.m. daily, but it's not open long: last call is at 9:15 p.m. Sunday through Thursday and 11:15 p.m. on Friday and Saturday. Hours are limited because the hotel is surrounded by apartments, many of which have balconies. But right after work, it's worth heading over, ordering drinks and watching the sun reflect on the dome of the National Basilica.
