Several years ago, an SCA member wrote an article for her kingdom's newsletter about eating lunch at modern food outlets, as seen from the eyes of a medieval gentle. Excerpts reproduced below, with gracious permission (remember that in medieval Europe, corn and potatoes were unknown, and tomatoes were not thought edible). Try to guess where they are. Answers below:
 

1) At several establishments, there is served a small remove all in one portion. Obviously, one is expected to order several of the available removes. Most of the main courses consist of a pair of small bread trenchers, small enough to hold in two hands, with amounts of several foods already served between. There is something that is probably meat with other things mixed in, that is cut into a precise round. On this round is spread a tangy red sauce, and in certain establishments, several raw vegetables in addition. There are also available small apple tarts, drinkable frozen puddings, and mounds of long, rectangular-cut sticks of some vegetable which was about the consistency of turnips. I must think for a while to try to determine what vegetable this must be. One of the establishments is a Royal Grant, it seems; the servants, each in identical livery, even distribute coronets made of heavy paper to the children, apparently as a reminder of this king's generosity in appointing the grant...

2) Each establishment seems to have a specialty, and at one of these places is seafood. The fish served here is an illusion-food; there are sticks of what appears to be a kind of bread, but upon biting the bread, it is found that a piece of fish is inside. Not only is this fish boneless, but it is one piece, an amazing thing. This place also serves the strange vegetable sticks mentioned before, but here they are called "chips"...

 3) The specialty of this place is the chicken, boiled in oil of some type, and served up by servants in identical livery. The chicken is exceeding tender. They must have taken the luxury of selecting a hen that was still laying, or had a large selection of capons. The side dishes are very strange. One was a round, berry-like yellow object, served hot and with melted butter. One can only eat the nubbles, the core inself is inedible. Another was a paste of white vegetable substance, served with a brown gravy, and the last was a salade made of chopped cabbage and carrots in a fermented cream sauce...

4) There are many specialty shops that serve a dish made upon a flat, round waybread, smeared with a strange red sauce, and covered with cheese. The thing is heated until the bread is done, and the cheese melted, and is cut into pieces and served hot. In some cases, many chopped meat and vegetable things are added into the cheese before cooking, and none becomes a distinct flavor, but all are combined into a common taste. Very pleasurable...

...All these establishments serve, as drink, various dark-coloured liquids which are exceeding sweet, and have in them bubbles of air which appear as if from nowhere. These bubbles create the need to belch after drinking them, but seem to have no long-lasting effect...
