I tried this today just because I'm the area.
The slices are actually bigger than normal Pizza Hut pizza. They're decently sized. It was $5 for two slices, and they're around the size of a Sbarro slice at the mall or something like that. They package each slice is a triangular box that's about 10 inches on each side and the slice takes up most of it--maybe like 7-8 inches per side? They also taste different from what I remember about normal Pizza Hut pizza. It's thinner and crispier. When I went, they had about 6 different pies out that you could choose from (Hawaiian was one of them, but I didn't get it), which at least gives it something over other local shops that usually just have cheese or pepperoni by the slice. They also have wings and salads and stuff.
Anyway, maybe I have low standards but although it's not nearly the best I've ever had, I don't think it's that bad and I would consider going back if I want a quick takeout lunch.
