The good: Pizza by the slice. Good pizza too, right up there with the other New York style pizza joints in the area. A good variety of styles. We tried the meat-lovers, buffalo chicken, white, and cheese pizzas, and all were good.
Needs some improvement: For a place named "Slice House" that featured Pizza by the slice, it would be good to have the price for a slice of pizza either on the menu board or displayed next to the pizza slices themselves. The system for ordering was a bit chaotic, but that's probably just growing pains.
Overall I recommend trying it out. We'll definitely be back.
