This family-run garden restaurant is halfway between Polonnaruwa (6km) and Giritale (7km), so you need transport, but it's worth the detour. The 10 or so curries on offer are cooked on traditional firewood stoves and guests are welcome to poke around the kitchen and even get a free cookery lesson (come at 5.30pm).
Grab a drink, look for water monitors in the nearby creek and then wander the garden to see the organic vegetables, herbs and fruits that go into the daily buffets.
