It's a Subway, so no sense reviewing the food. Four stars is probably the top rating possible for this chain. That said:
The location is great. Right next to the 51. I like to go to nearby Country Boys, my favorite "super cheap breakfast" spot, and then buy a Subway sandwich for later in the day. Then hop right on the freeway.
The dining room is larger than most Subways. You can stay and eat here comfortably without being bothered by others waiting for their food. Clean and well kept.
Staff is friendly and efficient, at least I have never had any issues in my few visits.
