When you like to have more formal or special party, you can order “hors d’oeuvre” to catering services. The “hors d’oeuvre” includes 1 – 4 and costs at least 3000 yen. ( sample :  http://moegitei.boo.jp/order09.html ) It is so expensive that people tend to ignore purchasing the “hors d’oeuvre”. They order the “hanami bento” instead of “hors d’oeuvre”. One orders “healthy” bento, the other orders “less volume” bento and the other takes choice with individual taste.
