Phnom Penh struck me as still more of a take-out place, but the decor in the dining room is decent enough, and the well-spaced tables (11 four-seat tables and 2 six-seat tables by the front) are basic but clean and relatively new. Getting a nice pair of plastic chopsticks was a plus.
The food was below expectations, particularly for the price paid. My spring roll was very dry on the inside and the accompanying sauce did nothing to make it any better. For an entree, I went with the Mee Khmer with the assorted seafood from the "Cambodian Specials" menu. Nothing about the dish stood out from ordinary take-out fare, and I was disappointed with the amount of seafood included for a $15 plate of noodles. There were a couple good-sized shrimp but then only slivers of imitation crab and squid and pea-sized pieces of scallops.
Service is minimal, due primarily to the fact that one guy does everything in the restaurant besides the cooking (covering tables, manning the phones, and handling take-out pickups). Not that it was crowded--only two tables were occupied the entire time (including my table)--but things ended up getting dragged out.
