Yesterday being my birthday, and a Friday night with the dinner buffet being promoted as a Seafood and Prime Rib Extravaganza, we decided to visit River Rock once again. We've heard somewhat mixed reviews from friends and neighbors since then, most recently including many raves about how great the buffet had become. We first visited River Rock casino years and years ago, just after they first opened, when it was a small tent, maybe 100 slots, no food, and no alcohol.
