I went there a couple of years ago with my girlfriend and actually quite liked it. back then, the food was expensive, but still reasonable. and yes, it was probably alot better than those other tourist traps there in front of angkor wat. back then I would have given it probably 4 out of 5 stars. above average food. slightly pricy (paid like maybe $10-12 per person), but still reasonable and love him or hate him french owner.
so I went there recently again with my mum on my second trip to cambodia.
the food prices have SKYROCKETED (and that is more than just the amount of the already high inflation of cambodia). there are now only these 'set menus' which I reckon is the biggest rip-off of all time. these force you to spend at least $50 USD and buy all the unnecessary stuff you wouldnt, except if your at some wedding lunch. (3 courses, some random side dishes etcetc.). I dont know about you but when I go for lunch its one main course and a drink.
now you have to fork out a whopping $50 to get some peanuts, some random salad, some wine and some other BS... and seriously: $50 USD for a meal in cambodia is unheard of. I mean even in berlin, germany where Im from u can eat out for half that price. and its cambodia we're speaking about here. to be honest. I felt ashamed of myself for eating at such a pretentious place and Im sure the waitress was wondering how anyone could spend such a copious amount of money on a meal. and yes: it was a bit better food-wise. but still average overall.
and yea the owner: oh well. try and avoid him. hes grumpy and tells you about how bad everything is (the economy, his restaurant, the authorities blablabla). not exactly what you want to hear when ur on holiday...
