I ordered a breakfast burrito, hash brown, SEC biscuit, pumpkin creme pie and a strawberry banana smoothie. Fast service, easy to use kiosk, workers friendly. I haven't been to this location since I moved away but anytime I come back to town, I'll definitely visit this location.

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 :)

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.

I mean, it's McDonald's food is pretty much the same at of them. But the employees here are courteous and efficient. The lobby is always clean and right now for Christmas they have really gone out of their way to decorate.

No one will wait on you inside of the restaurant. They will just look at you and ignore you. Waited five minutes before saying anything. I was told it was because I was on my phone, which I was not!!!!! I only had the app pulled up to show her. Not once did I not make eye contact with her, no texting, no talking. Both my husband and I just waited and kept making eye contact. Customer service is not available here!!!

MenuPriceTracker vs. Delivery Apps & Other Price Sites

How do these prices compare to what Uber Eats, DoorDash, or Grubhub show?

Uber Eats, DoorDash, Grubhub, and Seamless inflate McDonald's menu prices by 15–30% on top of the in-store price before adding delivery fees, service fees, and tip. The price you see on a delivery app is not what McDonald's charges at the counter. MenuPriceTracker shows the real menu price from the McDonald's app — what you'd actually pay walking into the restaurant or ordering at the kiosk.

Why not just check TripAdvisor for McDonald's prices?

MenuPriceTracker tracks store-level prices for 9,200+ US McDonald's locations across all 50 states, refreshed monthly from the McDonald's app.

Where does MenuPriceTracker get McDonald's price data?
