While several spots can justifiably claim to serve up the best burger in Berlin (the Bird, Burgermeister, Shiso Burger), there is something effortlessly simple and exquisitely tasty about Tommi’s version that makes it particularly good. The limited menu, handwritten on signs above and to the side of the counter, basically consists of the extra toppings (bacon, avocado, cheese) or sides (fries) you may want with your handmade patty of organic Scottish beef. The burger is flame-grilled and placed between a soft, freshly baked bun filled with crunchy lettuce, tomatoes, and other delicious additions. Despite the American-influenced, casual shacklike interior, this place is actually run by an Icelandic family that has similar outlets in London, Copenhagen, and Reykjavík.
