As good as melons are to eat, they’re even better when they infuse a drink. And the watermelon-infused vodka at Saga, an unassuming neighborhood bar just steps away from Grand Central Terminal, is hard to beat. Made on the premises, this flavored vodka is a delicate combination of fruity and sweet – with a potent kick that you may not notice until the morning.

“It’s not just watermelons sliced up in vodka. There’s sugar and brandy in there, too,” said owner Rob Meller. “We just do whatever fruit is in season.”

The infusion process takes about two days, and Mr. Meller uses Absolut vodka.

Whether it’s served on the rocks ($5) or “up” with a slice of watermelon ($8), it’s a cool answer to a hot summer day. The scene at Saga is relaxed and “Cheers”-like, with dim lights and good air conditioning. It’s open late – until 4 a.m. – and serves a full dinner menu until 3 a.m.

Saga, 329 Lexington Ave., between 38th and 39th streets, 212-682-8288.
