    We went to the McDonald’s on Main Street in O’Fallon, and I really liked this location. As soon as you walk in, it feels clean, welcoming, and like a place where you could actually sit and hang out for a while. I ordered through the app, and our food came out quickly, hot, and correct, which is always a win! The food was exactly what you would expect from McDonald’s, but it was fast, convenient, and did the job of feeding our group. What really stood out to me was all the different seating options. There are several areas where you can sit, including a large table that would be perfect for a group or even an after-game gathering. You can order at the counter, through the app, or use one of the kiosks, so there are plenty of options depending on what works best for you. They also have two interactive tables that change colors when you touch them. Kids can play with them while they’re waiting, which I thought was a really fun touch. Then, near the bathrooms, there’s a touchscreen with different games. This is especially handy when you have one child in the bathroom and need to keep another child entertained while you wait! Overall, this was a great McDonald’s experience. The food was quick and hot, the restaurant was clean, and there were plenty of things to keep kids entertained. I would definitely come back to this location.

    I generally think McDonald's food is terrible. But every once in awhile I still like the fish sandwiches. It must be a humiliation ritual for me because every time I go to this local McDonald's they pull me around and make me wait forever. They no longer have children's play areas anymore. Food quality is terrible and they treat their customers like they are the enemy. Everything has a life cycle and McDonald's is on the end of theirs.

    One of the best McDonald's! Cameron and the staff working at 6:30pm on 9/12 were amazing—very kind, friendly, and happy when we stopped to get our food.

    Where do I even begin..... This location has subpar service at best. The morning crew lacks customer service awareness and seems to have zero training on how to make coffees that are on the menu. One would assume there is a procedure in place to make these coffees consistently, but there is zero consistency. They are usually extremely bitter, or in this instance, my iced caramel machiato was just cream and caramel, zero espresso/coffee. Or for example, I have ordered countless iced caramel coffees with extra caramel/extra cream, that have no caramel in them and they taste horrible. Management insisted they are making them the correct way, but they always taste horrible The previous McDonalds location I frequented , for the last few years before moving, always provided consistent coffees that had the ingredients in them that are expected when ordering these coffees. There just seems to be a lack of care and attention at this location. Hopefully management will take this review and use it to educate their crew. Its frustrating to pay for something over and over again that is less than satisfactory.
