Eh ... I'm not entirely sure how I feel about this place. I've been to slice of vegas twice now. Both times the wait to sit was entirely too long, so I opted for the to-go bar area instead. I will say that having this little bar area is great for people who want their food without waiting for a seat.
The quality of the pizza is only so/so (it's a bit too greasy for my taste), and the ready slices taste kinda stale. Definitely opt for making your own pizza if you have the time/money/friends to eat with you (because the pizza size is actually decent).
As far as trying anything else, I've only had the 'Not Your Mama's Garlic Bread' - which was a let-down (not very garlic-y).
Oh also, this place isn't cheap - but where in Vegas is?? But there is a saving grace - it's right next to a Fat Tuesday's - SCORE!
