Flatschers Bistrot und Bar

121 Kaiserstraße Neubau

If you don't mind shelling out €15 or so, this popular, high quality joint has perhaps the best burgers in town. You don't even want to know how much they charge for their steaks. All made from ethically sourced meat. Nearest public transport is Thaliastrasse, just two stops from Westbahnhof on the U6 line.  Might be wise to make a reservation
