OFF KEY TIKKI

"Sunset Sundays" involves hanging out on the sand overlooking the Patchogue River as reggae and tropical rock bands play. Watch a monster 4-foot burger get cooked on an open fire pit, then toast the sunset from an Adirondack chair with a frozen drink in hand.

"People have a resort mentality when they are here," owner Michael Bruemmer says. "It's very laid-back and friendly."

TREME

Known primarily for blues and jazz, this modern New Orleans-style venue branches out with indoor reggae nights on Fridays in the summer.

"We wanted to do something different and fun. There's a big appetite for reggae on Long Island," co-owner Eric Bruno says. "Reggae fits naturally with what we do. It's just the blues slowed down a little bit."

For the past 25 years, "Sunday Funday" has been a tradition on Fire Island, a day party before the masses head home on the ferry. King Wellington mixes covers and originals on Flynn's outside deck overlooking Great South Bay. Sip a Rocket Fuel ($15) -- a pina colada topped with amaretto and rum -- while sitting among the live palm trees by the tiki bar.

"Sunday Funday gets more popular each year," co-owner Tim Flynn says. "It started out as a nice Sunday afternoon and now it's a big party."
