We visited for lunch on a weekday, and we were the only group when the restaurant opened at 11:30 a.m. We arrived just in time, but the restaurant was almost full. The salad bar includes a salad bar and each person must order one meal, but there was a watermelon and a melon in the salad bar that said "Grandpa's watermelon" and was very sweet! Especially the prosciutto pizza! The prosciutto pizza was not too salty, but had a lot of prosciutto on it, and I thought it was cheap at only a little over 2000 yen. The location of the restaurant is a gravel parking lot on a slightly elevated hill, so be careful when entering.
It is a store that I want to revisit again.
