A McDonald's is a McDonald's, so how much variation can there be? At the Okemos McDonald's (the one on Okemos Rd), unfortunately, the answer is quite a bit. I have found this to be consistently one of the worst fast food restaurants in the area.
I work in an office park very close to this restaurant, and so it would be a natural place for my colleagues and I to grab a quick meal when we are in a hurry. There is, however, no such thing as a quick meal at this McDonald's. No matter what time of day you go, no matter how many employees are working, expect to wait. On one occaission I was the only person in the drive-through, there were no customers waiting inside, there were at least 5 or 6 employees working, and yet I still had to wait several minutes just to place my order!
Another time I ordered some milk and recieved a container that had expired 3 days previously. When I went inside to point this out, the workers discovered that ALL their milk was expired. How many other people drank this possibly bad milk before I pointed this out?
These are just a couple of the worst examples. At this McDonald's, slow service, mistakes in the order, and just generally bad food is par for the course. Go somewhere else.
