You can walk along the river, there are a variety of bars, restaurants, etc., which you can go to. We also found that some travel agencies here offer transferees a little better price than the hotel directly offers. There is also a restaurant in the metro station with some really delicious food to choose from. I love this place in Phnom Penh - a great place to stroll around the promenade or sit by the bench for a great view. I have been here twice, once after dinner in the evening, it was quite cool, and the other was before sunset the next day because I wanted to see the daytime view. It is close to the palace, museum and old town. The best time to visit is early morning or before sunset.
