Based on various customer reviews and discussions, here are three things people frequently say about Subway's food:
It is highly customizable and convenient: Many customers appreciate that Subway allows them to build their own sandwiches with a variety of toppings and sauces right in front of them, offering a fast, personalized alternative to traditional fast food.
The bread is often criticized as being subpar or too sugary: There is a common sentiment that the bread is bland, has a distinct artificial smell, or is of poor quality. In some contexts, it has even been legally classified as "cake" rather than bread due to high sugar content.
The quality of ingredients has declined (not actually "fresh"): Despite the "Eat Fresh" slogan, many critics and former employees argue that the vegetables are not always fresh, the meat is heavily processed and filled with preservatives, and the overall quality has gone down compared to competitors.
