We went to McDonalds on our way to Circus Circus. I remember eating at a horrible buffet at Circus Circus and didn't want to go there for breakfast.
I would avoid this place on the weekends. It was too chaotic we went on a Saturday morning around 11am.
We went a second time on a weekday and the lines were more manageable.
The workers call your numbers when your order is ready. However, there needs to be a better system. Our number wasn't called and our order was sitting on the counter for 10 minutes.
Oh well. Cheap breakfast grub.
