I came here to enjoy a sandwich and it was ice cold no signs of any heating was applied to it despite the fact that I asked for it to be toasted.

I had a great experience at Subway today. The restaurant was clean, the staff were friendly, and they prepared my sandwich exactly the way I wanted. The vegetables were fresh, the bread was warm, and the portions were generous.
Service was quick even during a busy time, and the employee who helped me was polite and patient while I chose my toppings. Overall, a simple but satisfying meal. I’ll definitely come back again.

I love coming here after my workouts because I can get a fresh protein-filled sandwich without feeling guilty. The ingredients taste clean and the bread is always soft. The staff are also super helpful especially when you’re trying to decide between sauces. Definitely recommend the Steak & Cheese with Chipotle sauce.
