I work in the vicinity so yes, I frequent this place quite a bit.
When you're in the area looking for something healthier, this would be the place.
The service is consistently "good" - nothing really stands out. Because of it's prime location - the lunch hours can get quite busy. I usually go after 1 - and to be honest - there has not been a long line the past few months I went.
Parking stinks so I usually walk, but if you aren't so lucky - keep in mind their lot is small and they share it with a drive thru Starbucks - you could probably do the math and agree - it STINKS!!
Also, this is a tiny location so if dining in is your thing then you may want to skip coming or prepare to wait and be cramped.
While Port-o-Subs isn't my favorite sandwich chain, I frequent this location because I haven't had an issue with quality, price, speed or service.
