Kourtney Kardashian displayed an unusual amount of cleavage (for her) as she and the rest of the Kardashian clan went out for lunch after catching a show Sunday afternoon in Los Angeles. 

Kourt is not one for such a revealing look, normally that's Kim ... but she was the conservative one for a change.

Nothing says "open for business" like an open blouse.
