Been here twice, not impressed.
Port of Subs is actually a very good sub shop. I've been to other locations in other cities, and other locations in Vegas I've been pleased.
I've been here twice and both times have been lacking. Last time I went they were out of wheat bread so I opted for sourdough. The sourdough was dry, dry, dry and like a brick. My husband ordered their "Pilgrim" sandwich, he only ate half. It's a play on Thanksgiving (turkey, cranberry, stuffing, and then grilled). He said it can't hold a candle to the Bobbie from Capriotti's.
Also, service is slow. I think this is because they have a drive-thru which typically always has someone in it. With the lack of workers this leaves the few employees they have to work a drive-thru and make sandwiches for the people coming inside.
Quality isn't bad - it's same as other POS I've been to. Location is small. Service is OK, but slow.
If it weren't so close to my house I probably wouldn't go back.
