Indeed, it is a fun park. gokart, darts, pool, minigolf, air hockey, pizza... 14 holes of fun on…read morethe minigolf track. It's been pretty crowded, but it was a saturday night. You need a reservation to get on the gokart track. So we didn't try it. It's electric gokarts, but it still looked like a whole lot of fun.
The prices are very reasonable (5€-minigolf / 7€ minigolf+gokart), they have food, drinks, and so on. Recommend it!
