The small rice bowl (茶碗, chawan), literally "tea bowl", doubles as a word for the large tea bowls in tea ceremonies. Thus in common speech, the drinking cup is referred to as yunomi-jawan or yunomi for the purpose of distinction. Among the nobility, each course of a full-course Japanese meal would be brought on serving napkins called zen (膳), which were originally platformed trays or small dining tables. In the modern age, faldstool trays or stackup-type legged trays may still be seen used in zashiki, i. e. tatami-mat rooms, for large banquets or at a ryokan type inn. Some restaurants might use the suffix -zen (膳) as a more sophisticated though dated synonym to the more familiar teishoku (定食), since the latter basically is a term for a combo meal served at a taishū-shokudō, akin to a diner. Teishoku means a meal of fixed menu (for example, grilled fish with rice and soup), a dinner à prix fixe served at shokudō (食堂, "dining hall") or ryōriten (料理店, "restaurant"), which is somewhat vague (shokudō can mean a diner-type restaurant or a corporate lunch hall); writer on Japanese popular culture Ishikawa Hiroyoshi defines it as fare served at teishoku dining halls (定食食堂, teishoku-shokudō), and comparable diner-like establishments.
