ISO restaurant; great view, not expensive, set meal, group

[Tawan77]

Samui residents,
I'm bringing a group of 28 to Thailand in the coming months and am seeking your restaurant recommendations for a group meal: great authentic Thai food, nice ambiance/view, not pricey/no frills. Looking for a set menu, family/table style dining (not individual plates). ~400b/person including something like:
- yam woon sen,
- tom yum, tom jeud daohu
- phad thai
- gaeng kiaowan, gaeng penang
- plaa duk foo, plaa pao
Anywhere btw MaeNam and Lamai. Thank you!

My staff and I love the food at two restaurants where we eat.

 

Tum Lai. On the ring road and almost opposite Bandon Hospital

and Krua Choengmon (not to be confused with Krua Thai in Choengmon)

We usually go as a group of 22 - 26 people and so I know that they can both cater for a party of your size. Prices are very low as well. Especially Krua Choengmon which is off the beaten track. It is on the road from Big Buddha to Choengmon. Soi 10 just behind the 7/11

 

No great views though. Just good food.
