    I previous managed restaurants and I will say this McDonald's is well run. I frequent this location several times a week particularly at breakfast and lunch. Line times are generally quick and there is definitely a sense of urgency to move customers through but never at expensive of customer service. I am recognized as "frequent flyer" and the staff is always happy to see me. I have a small dog that staff loves and spoils. It's always a pleasure to visit and I just wanted to thank them for their hospitality.

    ordered at 1am staff was there heavier set man at the 1st window said they close early, even though all the lights on and everything working and i already paid… check the cameras at 1am - 1:30am on may 5th tuesday. that worker is going to make this location lose out on alot of money. bad for business. looking at the other reviews seems like its a reoccurring issue

    Absolutely horrid. They only supply old buns, stale, cold fries served in stained containers and old cheese. We asked for extra onions and they gave us none while the buns had stains of sauces that we didn’t ask for. I believe they gave us burgers from someone’s rejected order. What a vile establishment, especially for a fast food place. We’ve tried speaking to the manger for a redo or a refund and she just cursed us out and used rude language after we tried explaining to her what was wrong. I wholeheartedly advise others to not visit this place, awful experience all around.
