Questionable origins aside (Hollywood's first tiki restaurateur, Don the Beachcomber, has also taken credit), the mai tai was the star of the 1950s tiki-bar craze. And not only is the rum, curaçao, lime, orgeat and rock-candy syrup drink still popular, so are the over-the-top theme joints in which to sip them. The newest place to indulge is Sunday's Bali Hai night at the Flatiron Lounge (37 W 19th St between Fifth and Sixth Aves, 212-727-7741). And the Zombie Hut (201 Smith St between DeGraw and Douglass Sts, Carroll Gardens, Brooklyn; 718-875-3433) offers a potent twist on the classic cocktail: a pink, slushy zombie made with two kinds of rum and pineapple and orange juices. Otto's Shrunken Head (pictured; 538 E 14th St between Aves A and B, 212-228-2240) delivers colorful drinks and drink accessories, while at Waikiki Wally's (101 E 2nd St at First Ave, 212-673-8909), you can grab a mai tai and get tableside hula-dancing lessons.Nick P.
