Does this restaurant sell individual slices of cake for take out or only whole cakes?

Both are available.

You can buy a slice but it is the best cake EVER so you're gonna wish you had the whole cake.

Will sell by the slice.

You can definitely buy by the slice

Yes.

Either way.

Both are sold

Both. But be warned their slices are huge.. so a single slice is enough for two or three people.

They offer slice or the whole cake for takeout and dine in.

I think you can buy it by the slice. Call them and ask them their take out policy.
