Start on the obvious underclings under the lip with the crack behind you. Pull on (not that easy), and slap for the lip. Traverse the lip left, slightly until you can mantle over. Some people top out right, but this is not the original topout (variation)

On the normal topout there is a high micro-crimp for the right hand that allows you to flip the left into a mantle.

This is a great problem worth seeking out.

On the Chef boulder in the same narrow corridor as Mecha-Streisand, but just to the right. When facing teh problem, Cream Horn will be roughly behind you.

Pads.
