Nearly five years after opening, chef Grant Achatz's groundbreaking restaurant Next seems as if it has always been part of the culinary avant-garde — ironic for a restaurant whose prix fixe concept changes every four months. There's nothing blasé about Next. You never know what's going to be placed before you by Achatz and his star executive chef Dave Beran — it could be anything from chicken liquid croquettes (elBulli menu) to the world’s best mac and cheese (Childhood menu). Well, technically, it will be neither, given that they're from past menus and menus don't repeat. But you get the idea. Next has paid homage to legendary French chef Auguste Escoffier; then it was a futuristic Thai menu; followed by Childhood; an homage to the now-closed elBulli; explorations of Sicily and Kyoto; "The Hunt,” a vegan menu; tributes to the Bocuse d'Or, the Chicago Steakhouse, and the restaurant Trio where Achatz first set out on his own; an interpretation of modern Chinese; and now, “Bistro.” Upcoming 2015 menus include tapas and "terroir."
Whatever it is, Next’s food is inventive and exciting without being gimmicky; likewise, the service is flawless without being fawning. But good luck getting in. There's an online reservation system for buying "tickets," but you'll be joining some 20,000 (yes, 20,000) other folks just as desperate and committed to scoring a table. If you get into Achatz's next-door cocktail lounge, The Aviary, in itself no small feat, there's a tiny chance that you might get a late table at Next. Or check Next's Facebook page. Most nights, they hold a table or two and sell them there. The catch? You have to be in Chicago already.
