We used to go often, but has been several years since our last trip. Most all larger casinos on the strip and the casinos downtown have good buffets with lots of variety. Used to be partial to the Golden Nugget buffet downtown as they had all you could eat shrimp. When we first started going the typical buffet was $1.99/breakfast, $2.99/lunch, and $3.99/dinner. No more. Prices are much higher, but still cheaper than most restaurants on the strip unless you want fast food.
Used to get an after hours steak dinner (good steak, baked potato, salad, rolls) at Binionโs downtown for $2.99.
