Nestled down the quiet backstreets of Soi Ari is a small glasshouse that looks unlike any other restaurant in town.

At Flat Marble (Phahon Yothin Soi 9, 061-695-9666) there's only room for 11 diners at a time. You can order delicately plated international dishes from the monthly-rotating a la carte menu at the marble countertop.

Chefs Peechaya Sukviboon and Fahmanunya Chatraphuti's current specialties include US prime rib-eye steak (B390/100g), black truffle spaghetti (B790) and chocolate creme brulee (B150). Reservations recommended and it's cash only.
