    Marty is a delight to see at the drive thru and I look forward to seeing him when I go in the mornings! He is very animated and very nice and he always puts a smile on my face :)

    Kids say very yummy and they like the toys and the activities. Smartly designed with the items for kids to play.

    They are so stingy with their bacon it’s crazy. Ordered via the McDonalds app, ordered 3 extra 2 half slices of bacon (should’ve gotten 6, or at the very least 3), and only got two tiny strips, so I got absolutely no extra. Paid 8 extra dollars for that! And there’s no way to get my money back. Very not pleased :(

    All we did was ask for the hot sauce for a burrito and it wasn’t in the bag so we politely asked for some and the lady at the window got an attitude with us and said “there was one in the bag” but we sat and looked and there was not. There was no need for the attitude and rudeness towards us.

    Like any other McDonald's, they serve quick and happily. What I enjoyed most is the speed it is served and how good it is.
