Burgers are delicious and better to have them cooked somewhere between rare and medium. You’ll also get a huge amount of french fries, American style, so not crispy at all (this can be the only downside).
Hot wings are also a good choice, but remember that they are very very hot!
Other good things to try are the draught beer, the Caesar salad and the cheesecake.
Nice atmosphere and the music is great (if you fancy old-school rock n’ roll).
Not super cheap as other burger places in Berlin but the price is still acceptable (10-15 euros just for the burger with fries). Check the MENU here.
To get a table you’ll always need to book it a few days in advance (if you are very lucky you might find a free seat at the bar).
