Difficult to find, at least for the Oslo taxi drivers (I've had at least two drivers who had never…read moreheard of the restaurant, nor could they find the address). Still, the place is very popular, and a reservation is recommended.
Plah is modern style, Norwegian Thai food at its best, even though its best has probably past the BBD.
Choose between à la carte (starters 105-145 NOK, mail courses 235-275 NOK), or opt for a 5 or 8 course tasting menu (495/545 NOK). A third option is to try some of the Thai style "tapas", or Street Food as they are called here, priced around 50-70 NOK per serving.
The menu is constantly changing, as it should be, but it is unfortunate that the "signature dish" (in my book), Svineskank (knuckle of pork), has been deleted from the menu.
Oysters Naturel, "Hoi Nang Rom" is good, but just plain lemon works better with oysters than sweet chili sauce. Why complicate a winning concept?
The pork neck, or svinenakke (as a poor substitute for svineskank), is decent, but not extraordinary.
All in all, good food, but not the best Asian in Scandinavia, or probably not even in town, and the price - 595 NOK/81 EUR, plus tip for starter and main, including two glasses of wine - is, as pretty much everything in Oslo, nothing less than outrageous.
