Della's is a very nice little place in the Delano hotel. Nice decor. The food was actually very good. I had the chicken and waffles and my wife had a salmon salad. Yes, it was pricey as many as noted but you're eating in a restaurant of a 5 star hotel in Las Vegas so I can deal with that.
My 2 star rating? The service!
The food took forever to arrive. The server disappeared never to return. Whenever we needed ANYTHING (refills, check, check pick up, etc), I had to go find someone. There were at least 6 staff members running around on a Sunday with a restaurant at best 1/3rd filled. PAINFULLY slow. It took an otherwise good meal experience and really brought it down a couple notches. I likely would never at here again based on this. Caesar and Wynn restaurants do a better job with service.
