You will find this place just behind the Royal Palace at Dam Square and to the left on Nieuwezijds Voorburgwal. Mostly notable by the big neon sign at the end of the alley.
The menu has an even mix between indica and sativa strains, but they tend to stick to the old school stuff like Cheese, Amnesia, Jack Herer, Orange Bud and Bubble Gum which seem to be overly priced compared to other shops in the centre, but the quality is usually good. The Cream de Maroc is usually very nice from here so worth trying if you are a fan of your hash.
There is also a couple of Volcano Vaporisers available for customers to use and bongs are also easily accesible.
