The battens are slidably engaged within first sleeves transverse to a longitudinal length on the canopy, and the poles are slidably engaged within second sleeves extending along the longitudinal length of the canopy. The unit also includes a cloth pad having edges shaped to form fit open edges of the table. A closure at the back end of the canopy extends beyond the back edge of the table. A bottom side on the closure which extends back to the table, a cylindrical stack extending downward therefrom to engage the exhaust exit of a hot pot resting on the floor supporting the table.
