In addition to promoting tourism in the Serbian capital both at home and abroad, the Tourist Organisation of Belgrade, or just TOB for short, operates several tourist info centres in the city. The most convenient for visitors is on Knez Mihailova pedestrian street near Kalemegdan, while those arriving by plane at Nikola Tesla airport will also pass one in the baggage claim area. If you don't see any In Your Pocket guides or maps on the shelves, ask if they've got any behind the counter as they seem a popular item with visitors.
