21 Pinchos Tapas Bar in the Markthal is perfectly accessible by all means of transport.
When using public transport, you can take a train to Station Blaak.
From Station Blaak you will already see the Markthal in front of you.
On entering the hall, you'll virtually walk into the 21 Pinchos unit in the front righthand corner.
Coming by car, you are best off parking in the underground garage, Ds Jan Scharpstraat 298 (entrance to be found from De Blaak).
Just follow the numerous signposts in the area with the text: Parking Markthal.
After parking, either take the central escalator staircase up, or use the elevators, which are positioned in the side of the garage. Both are easy to find.
