Just returned from dinner at this restaurant. My personal experience of the food is it is very average. Nothing exceptional by any means. We ate outside in the garden setting with very basic plastic table and chairs. We ordered 2 starters and 2 main courses and beers. The food was edible but nothing memorable. This was our first night in Hua Hin having arrived from a 3 day stay in Bangkok. We ate in much more basic and cheaper places which had far tastier food, and where I would return. I wouldn't recommend this restaurant.
Tip: if you do go try not to sit under the trees as the birds have a tendancy to crap on you! This happened twice to us during our one and only visit. The first time bird dropping landed in my husbands dinner, and if that wasn't bad enough 30 minutes later it happened again on his shirt. Not very appealing!
