Not all McDonalds restaurants are the same. This particular franchise is very inconsistient. I go here fairly regularly for breakfast and sometimes the food quality is good, but sometimes very poor. Sometimes I find a piece of eggshell in my food or it looks like it was thrown very quickly together with parts of it hanging out. Other times it is perfectly made and exaclty as I expect it to be.
Sometimes the restaurant is very clean and tidy and sometimes there is trash on the ground and in the fountain. Occasionally the service is very poor, with a long wait and clerks that have difficulty understanding even the simplest order (Egg McMuffin meal with orange juice).
While I have not had an experience so negative that I will not continue to go, I don't appreciate the lack of regualrity.
