No doubt the tiki situation in this town is a bit lacking. But that will all change — at least temporarily — tonight when Center City’s Rum Bar transforms into the tiki pop-up Duke’s Surf Bar. Owner Adam Kanter and Katie Loeb, the Big Kahuna behind the bar at Han Dynasty, and the author of the just released book Shake, Stir, Pour: Fresh Homegrown Cocktails will be fixing up 20 authentic tiki cocktails, that’s five sweet, five spicy, five sour, and five strong concoctions, for your drinking pleasure. A selection Polynesian small plates will also be available. Here’s hoping this turns into something permanent, or at least more frequent.
