    Everything was okay except the food, I got there at the time my food was supposed to be done (I ordered online), my food wasn’t even started with basically nobody there (i had been waiting outside for 10mins prior). The boy working make the sandwich terribly and I used to work there so I would know, on top of the food being late he toasted my food with the veggies and sauce on it, so the bread was soggy and he didn’t know how to properly cut it either which let most of the stuff on the inside leak out and make it more soggy.I couldn’t even eat most of it.

    I had a disappointing experience at this Subway location. The bread wasn’t properly baked, the lettuce looked wilted, and there was too much ketchup despite my request for light sauce. Overall, the sandwich felt rushed and messy. I hope this location pays more attention to quality and customer requests.

    Got bread and cheese substituted for something different than I ordered. Never confirmed with me or told me about it. Found out after I opened the sandwich after I left. And they added onions and didn't put on the spices on a different sandwich. Went back and was told there was nothing they could do about it. So I got charged for sandwiches that I didn't order!
