ah bro....now my interested fanned into flame again. Let me look into this after the New Year. I travel with my wife though, so heavy duty drinking/bar fines are all out of the question...
It will be mainly makan and a little shopping.
If makan is a priority, here are a few recommendations-
New York Steakhouse probably has the best steaks in town. Their beef is properly aged, 30 days I think. Good selection of wines. A bit steep but you'll not find this quality/price in SG.
Without a doubt Hachi at the Sofitel is the best Japanese in PP. A couple of rungs down Wasabi on St 169 just off the main Kampuchea Krom offers the best all-you-can-eat ala carte Japanese buffet. Teppanyaki, sashimi, sushi, the works, in a nice setting.
Cambodian restaurants? I don't really go for it as I find they are too reliant on sugar and MSG, but fish amok is often touted as a must-try. It's a little like our otak, you know, lemongrass, turmeric, coconut milk. Lots of their cuisine is flavored with prohok, much like belacan but made from fermented fish instead of shrimps. Quite pungent but if masked with lots of basil, sawleaf coriander, is actually quite palatable.
Quite a number of Chinese restaurants here, some Cambodian-Chinese run, many from Hong Kong, lots of smaller Mainland ones. For good wonton noodle, try Sam Too close to Phsar Thmet (Central Market), their dim sum is not too bad. Tai Tai, Porkei, along Mornivong are popular destinations for both expats and locals. Game is offered but it's a hush hush game only for those in the know.
There are a handful of Singapore & Malaysian restaurants - Klang Boy near Phsar Thmey, Nanyang at Casa Hotel, Asian Spice at St 111, Hometown on St 154 close to the Golden Sorya Mall (not Sorya Shopping Ctr although they're quite close by), Sophia on St 180, and a few more not far from the entrance of to the Pochengtong Airport.
On the riverside something you'll never find in SG - Happy Pizza. What makes the pizzas happy? A certain herb which is sprinkled on as a topping. Choice of Happy, very Happy or delirious.
