I originally loved Slices when they were a newer brand, but I feel like they haven't done a great job of keeping up in the market.
Their employees are never friendly, the pizza is inconsistent, but if you do get a good one heated to the proper temperature, you're going to love it.
I wish it was like it used to be when it was always the same high quality pizza rather than feeling like a greasy quick pizza joint like it does now.
