This place has been everyone’s “best kept secret" for twenty years. Foodies from all over Athens have tales to tell about how they first discovered it way back when only Thai expats and drifting sailors from the nearby port walked through the door. Rouan Thai’s humble but by no means dreary appearance—it looks like a southeast Asian canteen—masks the fact that this is the best Thai in town (superior even to some of the city’s most upscale Thai restaurants; although don’t go expecting street food prices). If you feel overwhelmed with the selection on offer, you can’t go wrong with the excellent Pad Thai. Soup lovers must try the sweet and sour Tom Yum and the fragrant Tom Kha Gai. Don’t forget that the green and red curries are authentic—which also means authentically spicy, so keep a steady supply of steamed rice and jasmine tea to hand.
