As someone who loves Asian cuisine, I'm always happy when a new Asian restaurant opens in Siargao. Just recently, a Vietnamese place opened.

Saigao offers a taste of Saigon in Siargao Island - thus the name. 

Drunken Noodles - PHP250
Fresh Tofu Spring Rolls - PHP160

Vietnamese food is not really my favorite type of Asian food, but I still love it. I find Vietnamese food very flavorful and it has lots of interesting textures.

Overall, I loved the food here. I think everything was reasonably priced because of the taste and the serving sizes.

I would recommend Saigao. It is located in General Luna Purok 1, near the municipal building, gymnasium and the port.
