Reuben's home? (4)
I believe the answer is:
deli
'reuben's home?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for deli that I've seen before include "Food shop or counter" , "Exotic food shop" , "small food shop" , "Seller of unusual foods" , "Shop selling foreign foods" .)
