Emporium vs Delicatessen

Emporium (medieval Latin from Greek emporos = 'merchant') is a term used for a store selling a wide variety of goods, and for marketplaces or trading centres in ancient cities.

Delicatessen is a term meaning "delicacies" or "fine foods".
The term delicatessen has a secondary meaning in some countries, referring to stores that sell delicatessen; the word delicatessen thus also is used as a shortened term for delicatessen store. Sometimes this is further shorted to the informal term deli.
