Colorado Belle also has good food in their restaurant upstairs with riverview seating available.
IHOP across the River also. Buffet in the Tropicana was good the 2 times we ate there. Restaurant overlooking slots in Tropicana was very good.
River Palms had a good Buffet(Plenty of fresh fruits and pastries)- also the River Palms Cafe downstairs. Buffets are usually good if you get there at the right time when food put out is fresh. Otherwise you take your chances.
