You can get great food near Nieuwmarkt! On most days the temple in the Chinatown part is open as well (although it's a bit small). This street has more interesting shops compared to other streets (not the usual tourist gift shops) At the square (The Waag) you'll find more cafés and terraces. Sometimes even a market.
It's a bubbly street, not just because you can get great bubble tea here. But definitely worth checking out (it's right next to the red light district by the way)
There's a cute little market once in a while at the square (next to The Waag).
