My husband and I tried it yesterday. We stopped by for the all you can eat pizza lunch special.
They advertise it as $4.99 ALL YOU CAN EAT pizza but the reality's that's just cheese pizza. If you want to add toppings to your pizza slices then it's 50cents per topping. We each had 3-4 slices with an extra topping on each of them.
The pizza itself's not bad. It's a very thin crust and it comes out hot (very hot). Our waitress stopped by frequently enough so we could keep ordering pizza whenever we wanted. The first order's 2 slices, the next ones come at 1 slice per order (I guess to avoid waste?). Anyway, the slices are HUGE. I ate 4 of them and I was so full the rest of the day.
I had green pepper, bacon and sausage (divided, one topping per slice, green pepper twice) and green pepper and bacon were my favorite. I found the sausage to be too salty for my taste but that's probably just a personal preference, though.
Overall, it's not a bad deal but it can get expensive if you want to add several toppings per slice. The place wasn't too packed and the staff was nice. It's an OK spot to get lunch if you're in a hurry because the food comes out quickly and it's affordable too.
