Extremely extensive menu with many options to fit all tastes and levels of hunger (the double burgers are truly massive... 400g of beef). They tout their "dry aged bio black angus beef" but honestly I would pick the patties at BBI, Burgermeister, or Heat & Beat over these (larger) patties anyday. The interesting, and often extremely delicious topping/extra sauce combinations are what set Lily Burger apart. Do expect to pay a bit more than you would pay at Heat & Beat, Gorliburger, or Burgermeister but similar amount to BBI - however if you get a double burger with a lot of toppings you might end up paying 18 euros for one burger (you will definitely be full but you will also be broke). No beer (you can walk down the street to the spati and bring it back) and no bathroom so heads up if you need either (and you probably need both, eventually!). Friendly staff and usually a younger crowd. Expect to wait if you are coming with more than two people.
