SuperFly is located in Hoofddorp, NL not too far from the airport. They have a relatively small selection compared to standard Amsterdam shops. The staff was very friendly, and even offered a free pack of cones after realizing that the selected product was actually out of stock.
The Super Silver Haze was recommended, but appeared to be improperly cured - while the effects were fine, the taste and smell left much to be desired.
The environment itself is fine if you enjoy being in popular bars; the music is loud, the energy is high and the lights are bright.
