Vessel you don't want to go to (3)
I believe the answer is:
pot
'vessel' is the definition.
(type of container)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for pot that I've seen before include "prize" , "Cannabis; sink (snooker)" , "Shoot; pan" , "Cooking utensil or illegal drug" , "Substance from the sap of trees" .)
