This place is located behind Hinone Mizunone on King st and Sheridan. It was a super random find, but it was pretty good especially for $7 each. The only downer is parking is pretty bad. It seems like all the good eats have terrible parking lol.
Sheridan runs parallel to Keeaumoku st behind Walmart. If you are driving down King st you make a right onto Sheridan and the wagon is on the right side just past Hinone Mizunone Restaurant parking. I believe it has a rock driveway unless they upgraded since the last time I went.
