Kendall Yards has some great restaurants that are along the Spokane River.
Coeur d'Alene Casino has a hotel that over looks Coeur d'Alene lake. This casino and hotel is about 45 minutes from the venue, but the drive will take you through downtown Spokane.
Downtown Spokane has lots of history and great hidden gems; The garbage goat, Red Wagon, The Historic Davenport Hotel, and The Loof Carousel just to name a few.
This casino is the host of many of the concerts that come to Spokane. It is a great place to stay and have some fun while not being far from the wedding venue! The resort and casino is about 15 min away!
This casino and hotel is one that I have not frequented yet, but I have heard from many that it has great food in the restaurants! This place is also to the wedding venue, just about 10-15 minutes from the venue as well.
