Pacifico is a small town in Siargao, a little over an hour away from General Luna. Pacifico is home to a nice surfing spot, several hotels and homestays, and a lot of restaurants.

Wantaw is a popular restaurant in Pacifico. It has a nice beachfront location with al fresco dining areas, so you can enjoy the view of the sea while eating. You may be able to see some people surfing too.

Wantaw has a Japanese menu - it is one of the very few places in Siargao that serves Japanese food.

Veggie Ramen
Tuna Onigiri

The food in Wantaw costs from PHP 150 to PHP 350 per dish. The servings are a bit generous and the food was filling. 

However, the taste can be pretty inconsistent. I've dined there several times. Sometimes the food was really good. Other times the food was really salty. Plus, the serving times can be a bit long especially if the place is crowded.

I can't vouch that the food will be really good when you go there. Like I said it can be inconsistent. But if you are in the area anyway, might as well check it out.
