Stick around entrance to restaurant, but go without food (6)
I believe the answer is:
starve
'go without food' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for starve that I've seen before include "Die of hunger" , "Eat nothing" , "Averts (anag)" , "Stop feeding" , "Suffer from lack of food" .)
