If you are shopping at Albert Cuypstraat market (the oft-mentioned and seemingly favourite Amsterdam street market of Trippist writers, thanks to it many colourful offerings), make sure you take time out for a healthy break.
The fresh squeezed orange juices, at 1 euro a pop, will give you a better energy boost than a coffee. Also available at certain stalls are blends (1.50), all with an OJ base. Sample the OJ and pineapple, OJ and kiwi, OJ coconut cream and pineapple, and OJ and strawberries. Delicious!
