No, they don't do slices.
I usually end up taking half the individual pizza with me. If I am hungry I can eat three-quarters of it and take the last piece along.
There is a "pizza window" outside which is open when it's busy and sells only slices, but it is not the same pizza served inside the restaurant. It is thick-crust Sicilian style pizza and the reviews of it are, in general, not good.
