Even though it has a Main Street address in Southampton, Blu Mar feels miles away from the hustle and bustle of a major road. The inside features soaring ceilings, and the outside patio, with its linen tablecloths, conjures up images of dining in Greece or elsewhere in the Mediterranean. The restaurant, owned by Zach Erdem of 75 Main, also in Southampton, specializes in Mediterranean seafood, with a mouthwatering menu featuring fish in all its forms. And now, a touch of the East comes to Blu Mar—a sushi menu, which will be available in the new Buddha Lounge at Blu Mar, a more casual area featuring a tent, comfortable seating and the ability to order drinks and appetizers for those looking for lighter fare.
