Tonsai Restaurant – Klong Prao Beach – Restaurant Review

Tonsai in Klong Prao Beach is generally thought to be one of the island’s top restaurants. It’s located up by the entrance to Centara Tropicana Resort in the main strip of Klong Prao that runs from the temple, 7/11 and tourist police office.

The restaurant only opens in the evenings and we turned up fairly late for Koh Chang (after 21.00), but it was still busy with diners in both of the two seating areas. It’s a roofed but al fresco affair, with pieces of art hung around and about and even a small gallery on one side. With the tablecloths, starched napkins, bamboo mats, low lighting and laid-back music, it all projects a nice Koh Chang relaxed sophistication.

The Meal at Tonsai

The menu is extensive, with starters, mains, desserts, salads and lots of vegetarian options. For starters, we decided to share two classics, pomelo salad with prawns and chicken in pandanus leaf.


Pomelos are abundant in Koh Chang, orchard after orchard on the east side of the island grows them and there are some delicious sweet varieties, alongside the more common sharp tasting ones. Whether this was local produce or not, the waitress wasn’t sure but the dish was delicately assembled, a dressing of lime, tamarind juice, sugar, fish sauce and a hint of chili complementing and not overpowering the pomelo and poached prawns.

Finely sliced lemongrass, a surprise, as Thai cooking is stringently disciplined about what constitutes each dish and even the slightest change, this addition, can be frowned upon – here, though, it was a nice touch.


Chicken in panadanus leaf is another well known appetizer. The pandanus leaf grows easily in Thailand, it just needs a good water source and in this dish, you use the leaf to wrap little pieces of chicken, marinated in coriander root and soy. You then steam these parcels, then deep fry them and serve with a spicy dipping sauce (nam prik). The pandanus leaf imparts a wonderful smoky taste and aroma. Tonsai presented it beautifully.

The Main Courses at Tonsai

For mains, we plumped for a couple of curries, a simple seafood soy noodles and a veggie option.

Always listed in top ten favourites, Massaman chicken curry, this time with chicken, is the Thai Muslim dish that leans heavily towards Indian cooking, using spices such as cumin, coriander, Thai cardamoms and cinnamon in the paste. Tonsai cooked this well,, not too spicy and a generous use of coconut milk. Pleasingly, the chef also left the meat on the bone, making for a fuller flavour.

Red curry with duck, a delicious combination of roasted duck and pineapple in a coconut red curry sauce, is not as well known as Massaman . Yes, it does sound a bit like a blast from the 70’s, but if prepared properly, the fattiness of the duck offsets the sweetness of the fruit, with a hot kick running behind it all from the curry paste. Tonsai’s version was good, but maybe the paste could have been somewhat bolder, which would have given the curry more fire.


We chose tofu fried with holy basil as out vegetarian option. Here, the tofu replaces minced pork in what is another classic day to day Thai staple, normally cooked with yard long green beans and chillies. Indeed, this was what we were expecting, so when it came more as a tofu stir fry with vegetables and a little bit of basil, we were a touch disappointed.

The seafood noodles, always made with the wide rice variety, is a simple dish but it was perfectly executed. We also shouldn’t forget the presentation of the rice, shaped on the plate in sweet little conical banana leafs, another fun touch.

For drinks, we went for some cocktails, a pink lady and a mojito, both looked good and importantly, packed a punch. Fo the non drinkers, it was refreshing to see a menu offering a pot of green tea, a terrific drink with spicy food.

Service and Bill at Tonsai

Service, though understandably a little slow on a busy night, was charmingly polite and helpful and we took our leave, more than satisfied, around 23.00 after a long leisurely evening, though there were still another couple of tables chatting away, it’s that kind of place.

Overall, despite a few minor points, for us, Tonsai remains firmly established as one of Koh Chang’s top Thai restaurants.
