I learnt of this (chinese cum thai) ala-carte buffet lunch promotion  from a friend's friend and brought my family there, though we are not exactly big eaters.
It costs S$158 for 5 persons (inclusive of all additional charges and free flow of chinese tea).

The menu has 2 sections, first list has a limitation of 1 serving per table (and it iterally means each person has only 1 serving size or 1 piece, for countable items) and the second allows unlimited orders - and you can even customize the serving size / quantity being served.

In the first list, I think I like the braised sea cucumber with yam most as I think the texture of the sea cucumber is just nice - not too soft or hard. The yam is a bit too dry though. Everyone gets a bowl of the braised shark's fin but the quantity of the shark's fin is not a lot, which is not surprising of course. Except for beef, we tried all other items and the least favourite should be the steamed tilapia with thai lemon sauce, we thought the sauce tasted weird ;p

From the second list, we tried the seafood tom yum and I say, it is more sour than spicy. The fried sweet shell with XO sauce is my favourite from the lunch. It is chewy, spicy and tasty enough.

The fried sakura chicken with tri-sauce in stone pot is a disappointment though. The chicken meat is not tender, and the sauce is too salty. The fried pumpkin with golden salted egg yolk did not excite me as well (I ever tried crabs with salted egg yolk and I think that is very tasty). Other than that, we thought the stewed e-fu noodles with chives is bland.

There isn't much ingredients in the stewed seafood vermicelli with fish gravy but I thought it is quite tasty as compared to the e-fu noodles (cos we had the e-fu noodles before the vermicelli haha). At the desserts corner, the fruits are not sweet but there are other desserts to sweeten you up.

Basically we only manage to try half the items in the menu. We could have tried more if the kitchen really serves the serving size as we requested. For eg, I asked for 3 serving sizes of e-fu and chicken each, and 2 serving sizes of vermicelli. However all 3 items arrived as if they served for 5! When we asked the waitress, why is the serving size for 3 same as 5, she just smiled it off.

Another thing to note about the services, the waiter is quick enough to refill our tea often but they are also quick enough to clear the plates. Hence we felt like we are being chased to finish the food quickly. However, I find it amazing that we did stay there for 2 hours! And yes, I suffer from a full stomach for the rest of the afternoon...

Would I go there again? It will depend on the menu and pricing then.
