You can drive there yourself. You can also rent bikes and cycle there and back.
The menu listed here is everything they have if you go there.
It isn’t the chain, it’s a local independent family restaurant with an entire Japanese menu.
Open all year for lunch and dinner (until 8:30/8:30). (Think last order 7:30 – 8:00). Super Delicious!
