Belgrade, as it is not served by any low cost airlines, is spared the stag dos and hen dos that fill other eastern European cities. As such, its tourism is lower volume and less crass. The city is served by a good network of Trams, which are surprisingly thiner than the average tram in other cities.
The streets are full of vendors, selling books, bracelets or food from walls or small displays. They don’t bother you as you walk by, expecting you to be interested and the content is generally targeted at locals.
Gambling is a huge past time here it seems and there are a great number of slot machine venues scattered around the city.
