I've been obsessed with Port of Subs since I was like 8...and I've also ordered the same sandwich since...I was like 8.
There's something about Port of Subs that just makes them taste better than any other sandwich shop, I think there's a secret to that mustard/mayo mix (it's delicious).
When we moved to Centennial, I was totally stoked to find out about this location practically down the street from my house, so you can say I come in a lot. The staff is always really friendly and this is a very clean location. We had a family barbecue this past Monday and I was way too lazy to make my own potato salad, so I called this place the day prior and for a 3lb? order that feeds up to 10 people it was only $10! And of course it was delicious.
