The First Kitchen Two Face marketing strategy puts a traditional fast food face on their locations in shopping centers to appeal to families (read children) and school girls, while on shopping lanes leading to train stations, the stores have a slightly more subdued appearance and offer items such as pasta to attract business people and older students. They appear happily bliss to the negative connotations associated with Two Face in English.
