Review for Morongo Casino Resort & Spa Review For Potrero Canyon Buffet Google User Apr 24 '18 at 6:13 By far, not the best buffet that I've been to. The 2 starts is only because the prime rib was very good but, everything else was less than average. While there were a lot of desserts, they really weren't that good. We should have gone to one of the other restaurants in the casino. Not going back. View full site to comment or like
