    I ordered a sausage burrito with picante sauce pack and bagel with butter. They made me go park in the waiting area for several minutes. No picante sauce and no butter on the bagel.

    Food was typical McDonalds quality. Service was slow for not being very busy. Layout of dining seems awkward and confusing.

    thank you Alejandro for the help. He picked up his phone very promptly and answered the questions that I need. And he is very polite when answering the phone, although I did not intend to purchase anything at the meantime. However, I’m a regular happy meal customer.

    Order around 1pm yesterday and it took 20minutes to get my order. I probably would not have gotten my order if I didn't say anything. I went up to the pick up shelf and the girl on shift with highlights wearing the safety vest gave some attitude when I asked about my order. I was going to say something else, but she turned around before I could say anything else. It wasn't until then did they start working on my order. I saw my order just sitting there and when they were assembling it they are working SLOWLY. Like the girl was getting my items one by one and walking back and forth instead of just holding the box and adding the items. The nuggets were basically cold, fries were whatever, and the sweet tea was warm. I did say light ice, but it was basically nonexistent. 10/10 don't recommend this location.
