Long waits, slow service, poorly managed and mediocre food. You seem trapped and longing for simple fare at Mandalay Bay. They seem to know if because folks continue to line up here to eat breakfast and they do nothing to improve wait times.
Do yourself a favor and leave the hotel for Luxor's cafe or better yet, take the tram to Excalibur and walk to CoCo's next to Hooters. The walking will do you some good and you can enjoy a greasy chicken fried steak at half the price of Raffles.
