I assume you mean Big River Grille at the Boardwalk.
It would be very nice for a light dinner. The restaurant has good soups and appetizers, very nice sandwiches, as well as some good entrees. It is not terribly fancy, but a nice place for a meal. We go at least once each trip.
Oh, and don't forget the beer, which is brewed on site and is a nice change of pace from the rather ordinary beers available at most other WDW restaurants.
