Steven Sirski posted “Coffee and Coffee Shops in Asia”. The traveler wrote about a great place for coffee in Cambodia:
Hard to find a decent cup of coffee in PP [Phnom Penh] but, if you must, go to the Foreign Correspondent Club (FCC) along the Tonle Sap river. Found in a renovated villa from the French colonial era, the place is both a boutique hotel and a cafe. Get the double since a single is something like $2 whereas a double is $2.50 and is a generous serving of caffeine. Again, atmosphere is pretty cool and the service is great. The cafe is located on the second floor, overlooking the Mekong River, and out of reach of the hawkers working the street below. Lots of foreigners inside, lots of hawkers selling weed outside.
