Here is a pizza place where I'm living at the moment in Phnom Penh. It's called the happy herb pizza. It's on the riverside and has a great view of the Tonle Sap and Mekong Rivers. What gives it that extra special feeling is the 'herb' they use on the pizzas.
The pizzas are great tasting and come with all the regular toppings, nothing unusual every just pretty standard. It's a great restaurant with a great atmosphere.
One thing though, that extra special 'herb' is marijuana. You can get ganja mixed with the sauce or 'oil' made from the marijuana. It's not alone there are number of these types of restaurants in Phnom Penh and this is the original one still going strong.
