I really can't understand some of these reviews. We have just visited the Coconut and I came on here to say how good it was, the food was first class and the service was excellent - smiles all round and very efficient.
As for the cost, I think people need to realise that the days of the four course meal in Thailand for 150 Baht is long gone. We had an excellent meal and more than enough drinks for 1400 Baht for two of us, and I was well satisfied.
Ignore the bad reviews and give it a try your self - it is well worth the visit.
