Why locals love it?
If you want to have a drink right on the river, then this restaurant/bar with a beautiful view of Prague Castle is the right place. The interior of the restaurant is quite small but most of the people usually sit outside anyways, either on a bench or simply on the ground.
Why you should visit it
All generations and age groups come here. People who take a walk along the river and cyclists passing by often stop here for a drink or two before they carry on their way.
