Club H is a restaurant that's on a boat on Lake Herastrau. The lake is beautiful year round, but the advantage of being there in the summer is the lush greenery around the lake(the largest in the capital). The number of people ve are there doing outdoor activities, or just walking is great. The sun sets around 10 pm, so they stay out pretty late. What surprised me is that on a sunny summer day there were so many people on the boat. There's a covered part of the boat, and booths where you can sit and eat your lunch (and there was a huge storm half an hour later, maybe that's why people did not trust a lot).
