"Aoki's Forest Cafe" is in "Meiji Forest, Kuroiso" rest area and it looks like a Western-style building surrounded by green. You can have a handmade gelato and pizza there. We recommend you to eat on a terrace when it is a good weather!
There is some limited menu using foods in season such as gelato using Tochigi's strawberries and rare pasture gelato. In Autumn you can have mushroom pizza.
Why don't you try foods in season at a cafe surrounded by green?
Next to the cafe, there is "Old Aoki's house in Nasu" which is built in the Meiji Era and registered as Japanese heritage and Hanna Garden which has a lot of seasonal flowers.
