The term delicatessen has a secondary meaning in some countries, referring to stores that sell delicatessen, hence a shortened term for delicatessen store, sometimes additionally shorted to the informal term deli.
A grocery store or supermarket may provide its own "deli" food, or even operate a delicatessen on-site. Like a market a delicatessen may also offer a selection of shelved food, often of the type that is not likely to be kept for more than a day. Produce, when present, is limited in quantity and often fresh. The Deli counter of a supermarket is where many people obtain their cold cuts.
Delicatessen shops vary greatly in size but are typically not as large as grocery stores. In areas with high rents for retail space, delicatessen shops are often quite small.
Delicatessens can come from a variety of cultural traditions. In the United States, most numerous are Jewish delicatessens, both kosher and "kosher style." As a result of this, Americans refer to those that specialise in Italian and German cuisine as "European Delicatessens." In Seattle, Washington, the term "deli" is often used to indicate take-out restaurants mainly serving Vietnamese bánh mì sandwiches, particularly in Little Saigon and the University District.
Most delicatessens have a sandwich menu, most of which are made to order behind the counter at the time of sale. Delicatessens often sell their meats by weight as cold cuts, and prepare party trays.
In addition to made-to-order sandwiches, many delicatessens offer made-to-order green salads. Equally common is a selection of prepared pasta, potato, chicken, tuna, shrimp, or other variety of "wet" salads, displayed underneath the counter and bought by weight or on a sandwich. Precooked chicken, shrimp, cheese, or eggplant products, possibly fried or parmigiana style, are found frequently, though they do not constitute the mainstay of a delicatessen.
In order to provide an opportunity for a complete meal, delicatessens also offer a wide variety of beverages, usually prepackaged soft drinks, coffee, teas, milk, etc. Chips and similar products are available in some variety, though they rarely rival the selection of small package cookies and snack foods; some pre-packaged, others store-made and cellophane wrapped.
Alongside these primarily lunch and dinner products, a delicatessen might also offer a number of additional items geared toward the breakfast eater, including pancakes, bacon, sausage, waffles, omelets and baked goods (breakfast pastries, bagels, toast), yogurt, and warm egg "breakfast sandwiches". Newspapers and small food items such as candy and mints are also usually available for purchase.
In Germany, Switzerland, and Austria, "Delikatessen" (as it is spelled in current German) has a rather different meaning; it designates top-quality (and top-price) foodstuffs. A common synonym is Feinkost ("fine food") or similar to "Good Eats". The shops which sell them are called Delikatessenläden ("stores for delicacies"), and department stores often have a Delikatessenabteilung ("delicacies department"). You can also find Delicatessen in Denmark, Belgium and The Netherlands. None of these sells the take-out food that is characteristic of North American delicatessen.
In Europe, American Style Delis are provided largely by fast food outlets such as 'Subway'; this reflects the quality of produce available at these counters.
Because the original German word delicatessen is already in plural form, the English plural delicatessens effectively uses a double plural.
An alternative (apocryphal) popular etymology supposes that the -essen part of the word is in fact the German verb essen (= English: to eat; also German: das Essen = English: the food). This would mean that the word is a portmanteau of the German words "delikates" (delicious, nominative case) and "Essen". "Delikat essen" (with delikat as an adverb) is also a comprehensible phrase in itself in modern German, meaning "to eat delicious things".
