Couple of my favorite places/things to do in Reno:

1. Buffalo Progressive at Atlantis

2. Mel's Diner at the Sands (best to visit during daylight hours)

3. Jerry's Nugget (Sparks) -- good peoplewatching

4. Peppermill Slot Chairs -- like butter

5. Lake Tahoe is 1 hr away, but don't do the drive during rush hour or on a Friday or weekend day.
