In 2005, Achatz went out on his own, opening Alinea in Chicago's Lincoln Park neighborhood with Nick Kokonas. The restaurant is located up the block from the famed Steppenwolf Theatre Company and is housed in a modest gray brick building which bears no external markings beyond its street number. Inside, the restaurant has no bar, no lobby and seats just 64 guests. Achatz serves diners a small-course tasting menu, consisting of approximately 18 courses. After less than two years of operation, the Mobil Travel Guide bestowed its Five Star Award on Alinea, making Alinea one of just 16 restaurants nationwide to rate five stars for 2007.
