Reachable via a couple of pedestrian/bike bridges from the NEMO Science Museum, this cool, laid-back waterside cafe is built from recycled materials and has a fantastic leafy beer garden. Join the arty crowd enjoying the sunshine at brightly coloured picnic tables under the trees. If the weather's no good, cosy into a vintage armchair by the fire inside.
The site dates back to 1662, when it was a guard post monitoring maritime traffic into the city.
