Duran Sandwiches is an Austrian fast-food chain which has been around for a while. This place-located in the city center, near Deak ter-gets very busy at lunchtime as lots of people from nearby offices pop in for a quick bite. Over thirty kinds of sandwiches are on offer with fillings that include ham, cheese, caviar, shrimp, eggs and salmon. Pizza is also available. The sandwiches are tiny but delicious. This is a good place to use for catering if you are throwing a party.
