Oxymoronic as it may sound, pop-ups are now a fixture in our local landscape. Naturally for New Orleans, our chefs and restaurateurs first blazed the pop-up trail by finding new and creative ways to promote their creations, the vanguard formed by such establishments as MV Burger popping up at Slim Goodies Diner in Uptown, BooKoo Barbecue popping up at Finn McCool’s Irish Pub in Mid-City, and down on Frenchmen Street, the taco truck formerly on Washington Square Park now popping up in the kitchen of Cafe Negril. Economically, pop-ups are brilliant: little to no overhead, the buzz surrounding their appearance a burst of free advertising, and an opportunity to cater to a hungry public with a minimum of staff or long-term maintenance costs. But chefs take note. There’s a new game in town: the art gallery pop-up.
