You are looking for Sharp Shooting, an indoor range in Spokane at the corner of Trent & Freya, 509-535-4444. They have a 50' range, many gun rentals, and good prices on new guns. Also a OK selection of holsters and other accessories. A 1 day pass will run you $15. A 2nd shop, All American Arms is 250' away, compliments the selection of pistols and long guns.
The Cd'A lake is one of the jewels around here. So is Mt. Spokane, which is worth the 1 hr drive. Several good resturants in downtown Cd'A, also in Spokane. Clinkerdaggers, Steamplant, Bayou, Luigi's, Itialian Kitchen, Fugazzi, Patsy clark's, all do a good job. None are considered "eats", but there are very few places here that will even come close to breaking your budget.
If you have a only a few minutes and want to get a flavor of the surrounding forests and landscape, drive a few minutes past the Rifle Club mentioned above and stroll around the Bowl and Pitcher on the Spokane River in Riverfront State Park. Go across the river and walk on one of the several trails.
The rifle club is a place to shoot what you bring, but does not have any store or rentals.
Have fun,
Chap
