How did the lunch look like?

“To the Takashimaya department store restaurant in Nihonbashi.” …Midori and I went to the basement restaurant and, after a close inspection of the plastic food in the window, both decided to have an old-fashioned cold lunch assortment with rice and pickles and grilled fish and tempura and teriyaki chicken. ( Norwegian Wood Ch.10)

This is “the plastic food in the window” at the basement restaurant. The “an old-fashioned cold lunch assortment” may be that in the square bento box in the lower shelf.
