There aren't many dining options in Volcano. Luckily I was able to find this restaurant. They do a lot of pizza takeout order (no gf available) but have a number of other entrees that you can select from. The server wasn't super familiar with gluten free, but the chef had experience cooking for someone with Celiac so I felt good about eating there. I had the Ka'u Fish which tasted alright. Luckily I didn't have any issues here.
— No gluten-free information on the menu
