I had heard a lot about Tommi’s Burger Joint in Mitte, close to Rosenthaler Platz and finally went a few weeks ago. The place has quite an original decoration and a super friendly staff. I had a bacon cheeseburger, it was really tasty, good quality meat and the possibility to add (for free) a few sauces or ingredients like pickles and oignons and such. I also had a milkshake which was super nice. The only negative point is the price, it’s quite expensive, but still worth it.
