Luv A Sub is an unconventional little sub shop in the middle of an inconspicuous office park. The location can throw you off a little bit, because it really doesn't seem to belong. However, it's a good thing it's there because it's one of the few non-burger/fries joints in this particular stretch of Phoenix.
The food here is pretty decent. I've had three or four different subs here and they've all been tasty. Nothing mind-blowing, but certainly appealing to the gut. The food is pretty affordable, provided you stick with just a sub and get your drink and side elsewhere. Their menu, as has been mentioned in other reviews, is pretty extensive but unnecessarily so. They'd be better off presenting the customer with a handful of distinct sandwiches and then listing all of their toppings. They literally break out each variant of a particular sub and list it as a separate menu item, which ends up just being kind of overwhelming.
The people that work here are very friendly and the service is brisk, making this a hassle-free lunch stop for the businessperson on the go.
