Just had lunch at Open Wine - what a delight! Had an excellent three course lunch with salade de chevre, rumsteak with pepper sauce and french fries and a wonderful dark choclolate mousse for dessert - all for incredible $10. The restaurant also offers an excellent choice of wines by the glass (generous servings) at very good prices (French Merlot at $4 for a glass). The meat is by far the best I have in Cambodia. The dinner menu is more expensive than the lunch three course offering (at least twice the lunch prices), however if the level of quality I experienced for a quick lunch is any indication, it should still be worth it at the higher dinner prices.
Service was impeccable, efficient delivery of dishes and attentive serving of water and (warm) bread throughout the meal.
Having lived in Phnom Penh for several months, I'm sorry not to have found this place sooner. I'm flying to Paris tonight, but the next French meal I look most forward to will be in Phnom Penh.
