    I swear this one always has trouble with orders not just at the window but also making it fresh and or correct. The Older man manger could give to cares and always says well there is a language barrier so that's why the order is not right. Ok I get it for one time but every time. I miss how they could get something right. For them to get something correct would be asking like what 2 plus 2 is. I will now and forever go to the on in Lake St Louis they have great customer service and always get the orders right. Do better!

    This is the 2nd time that I arrive 10mins to 6a and eventhough they are open with workers inside they did not take my order at drive through. I sat for a 2 mins each time. Drove by the windows and I can see ppl inside. This is unacceptable. Starbucks across the street has better service anyway!
