Had dinner with my dad here the other night and (possibly aided by my significant hunger) came away pleased. The restaurant was clean with a surprisingly sleek decor. Peppered throughout the dining area were these paired flatscreens that displayed a rotation of neat panoramic images that I really liked. Despite being fairly busy (it was around 5 pm) the service was fair enough.
The house salad was a pretty lackluster jumble of the bagged variety (par for the course as far as casinos go) but this one didn't even have onions, carrots, or a tomato sparsely sprinkled about. I ordered the southern fried steak which came with a baked potato and "vegetables". Like I said before I was pretty hungry but the meal ended up being surprisingly good. The potato was a little dry but not enough to fuss over and I added some of my dads horseradish (he had the prime rib) to give it some flavor. I recommend getting the straight horseradish instead of the creamy stuff for that little extra kick. The "vegetables" turned out to be some bland green beans but some salt and pepper helped them trend towards mediocrity. The steak was a good portion and the breading wasn't super heavy. Also, they didn't drown the entire plate in gravy which I prefer.
Maybe my experience was elevated by my company (and our hunger) but I can safely say I enjoyed my experience at the Rainbow Club.
