Side Street Inn is really located on the side of the main streets behind Ala Moana Shopping Center. It is a local favorite because the local chef there really makes some good food.
The Inn is not exactly family oriented, but rather a gathering place for friends. They have beer on tab and the food goes well with it.
The more I ate at Side Street though, the more I felt that the food was a little greesy (of course depends on what you order). They have some fresh dishes on special such as steamed fish.
Overall, Side Street is a great place and showcases the talents of a local chef that wants to keep it small.
