I'm not sure if one Subway experience is ever drastically different from the next, but this one was average.
First of all, I went at noon on a week day, and it's near Cotton Center, so that's my bad. The "room" is very small, and the few tables they were able to squeeze in felt like they were literally in the assembly line or the doorway. Fill that space up with about a dozen hungry business people in a hurry, and it gets even smaller.
That said, the employees were keeping up quite well. The team was a well-oiled machine and we got through the line pretty quick. The friendliness of said team varied from person to person. My sandwich was exactly what I expected, since I ordered the same thing I always do.
If I go back, I'll go off the lunch hour. More likely, I'll drive an extra couple miles to the location on 24th St. and Baseline.
