Being generous with 2 stars.....
Below Average.....
This pretty much sums it up. If you want a below average meal, come here. There are so many better options in Las Vegas. I can only comment on breakfast which was pretty much standard fare. The food here is pretty much what you would expect from a local diner. I didn't think it stood out in anyway. I had the chicken fried steak and it was a bit rough (I didn't finish it) and had lots of gristle. The bacon was good though. The person I was with had biscuits and gravy and mentioned it was "soggy."
I will say that the service was very good. The atmosphere of the restaurant was quite well done (looks like they had an interior designer come in) and the outside dining area was very nice so I give them props for that.
The Tropicana is a nice hotel, and I would even consider staying there given the recent upgrades they have made. However, I don't think I'll venture to Cafe Nikki again.
