One problem that zoos have is that many animals are not active during the hottest part of the day when most of the visitors are there. The Singapore Zoo solved this problem by creating the world's first nocturnal zoo called Night Safari. It's a smaller zoo adjacent to the main Singapore Zoo, but it's only open at night when the animals are most active.
It was really interesting to see the animals move around at night. But it was also really difficult to take photos of the animals because flashes are not allowed.
Awesome dumplings. There was a Din Tai Fung restaurant next to my hotel. It was't really a goal, but I've now eaten at Din Tai Fung in four different countries.
