"Brutally local" is the cathphrase at what's currently Berlin's hottest reservation, opened in 2015 and already anointed with a Michelin star. Owner/sommelier Billy Wagner and chef Micha Schafer limit the nightly 10-course menu to ingredients from within about a 250-kilometer (155-mile) radius of Berlin. This means no pepper, citrus fruit, olive oil or chocolate—but plenty of fruits, vegetables and preparations you won't taste anywhere else, like pickled dandelion buds, ground ivy, and grapeseed oil cream. Take a seat around the massive open kitchen, choose meat or vegetarian, and prepare your palate for a challenge, especially in winter, when pickles, brassicas and sour and bitter flavors rule. It may not always be delicious or especially filling, but it's one of the most memorable dinners to be had in Berlin—especially if you leave the drinks to the ultra-charismatic Wagner, whose course-by-course pairing is a near-theatrical experience.
