Stick with the Sunset Grille... They have the best beef, and I've had the best steaks of my life there - and being a carnivore, I've eaten at most of the big name steak houses. Sunset uses USDA Prime which is the highest grade available.... LG's features UDSA Certified Angus Beef which is fantastic quality, but can be Choice grade rather than Prime.
If you're at the Radisson, you'll probably play in the Casino. With player's club points, you can probably get a comp for dinner. The comp probably won't cover it all (If you order like us) but will cut 2/3rds + off the bill. The 2 restaurants we never miss are Mme J's and Sunset Grille. We usually do Sunset toward the end of the week and use a casino comp! Enjoy.
