Review for Desert Diamond Casino & Hotel - Nogales Highway Review For Diamond Grill Snack Bar Google User Feb 6 '18 at 12:13 The Desert Diamond Buffet was okay. I kept going back for the steak. I did not see any Seafood the day we ate there. But they had some great tasting sweet potatoes and green bean casserole that I really liked. It is a good size restaurant with TVs but since we met up with friends when we ate there there is no need to watch TV. The desert bar was generally okay. They have the standard soft serve ice cream with pie slices and other desserts. View full site to comment or like
