Hollywood-based Bevvy.com, an invite-only site providing preferred pricing on bars and clubs, launched Monday, saying that it will provide a "Priceline for nightlife." The startup offers up 50% discounts on nightlife venues after a $10 reservation fee. Bevvy is headed by Niall Donnelly. According to Bevvy.com, users can find bars and clubs through its online reservation system, paying $10 in a reservation fee or $50 for bottle service, and then they will get a 50 percent discount at those locations. Bevvy.com also said it has signed a deal with Gilt City to power that site's nightlife deal in the coming months. No financial details of that deal were announced.
