I try to steer clear of fast food when I can, but sometimes they just sound so delicious or they are the most convenient to have. For instance, the daughter was hungry and I was in a rush to get ready for an event and this McDonald's was across from SLS, which at the day of our visit to McDonald's was not open yet and therefore did not have functional restaurants yet. We went through the drive thru and it was easy and manageable.
This is a typical McDonald's with nothing to make them more memorable than other locations (in a good or bad way). But if you are staying in the vicinity and in need of fast food, do try them. Their drive thru is also open 24 hours so they are very convenient if you need calories late at night (which happens a lot in Las Vegas, go figure!). Overall, not a bad McDonald's.
