Katherine's is one of three places to eat at the Casablanca Casino and Hotel. It is their fine dining steak house (the others are their Cafe and their Buffet). Their menu offers seafood, pastas and, of course, steaks. Four of us attended. First, the switchboard took my reservation, who managed to lose it. However, the assistant manager provided excellent customer service and immediately seated us, even though it was a busy Saturday. Once seated, the service was on a par to any fine dining...excellent. The ambience is intimate and comfortable bordering on tight, but it was crowded. The food, however, was inconsistent. Everything was ala carte with sides being $7 each. Our guests both had the Veal Parmesan and enjoyed it well enough. My husband had the prime rib that was cooked exactly as he ordered and proclaimed it to be the BEST prime he ever had. It was certainly the largest one he ever had coming in at least a pound and a half. His sides of baked potato and broccoli were unexceptional. I had prime the night before at Gregory's (the Steakhouse at the Eureka Casino, which was much preferred by all) and opted for the Chicken Fettuccine Alfredo. It was completely unimpressive with a broken Alfredo sauce and gummy pasta. Our bill without alcohol or tip was over $175. I gave Katherine's three stars based on what is available in Mesquite (in Vegas it would be a 2). If you want prime or steak, it is doable, but all of my party gave the service 5 stars (thank you Raul and your assistant), the ambiance 3 stars (we like the comfortable and intimate feel with sufficient lighting, but felt dated) and the food a 3 (mediocre at best except for the prime rib). Bon Appetit!
