I've visited here twice and love John Roberts. Mayfield location is surprisingly large with high quality accommodations. My mom and I went for a gel mani-spa pedi appointment, took a little over 1 hour in total.
Spa pedi: amazingly comfortable massaging chairs during pedi experience, toes were trimmed, polished and cleaned to perfection. Any rough spots on my feet were gone!
Gel mani: lots of color options, high quality work smoothing and preparing the nails, and excellent polish finish. Bonus: I learned that John Roberts will do complimentary gel polish removal later on - excellent service offering!
Prices are expensive, but for a special treat, especially if you buy packages with a discount, this is a worthy treat.
