I ate a lunch plate of minced meat cutlet at a domestic local restaurant. It cost 800 yen ($8.25 €6.25). There are cutlet, rice, miso soup, raw fish, and tofu on the plate. I ate it with other 5 friends. After the meal, each of us paid money separately at the payment. Some restaurants accept separate checks.
In Japan, luch time is usually from 12:00 to 13:00 (one hour). Restaurants are very crowded at lunch time. So we can not eat lunch in a relaxed state.
