Do you mean @Deeritna or @Deeritna Express ? Both are delicious anyway, they make a mean kubbeh with laban, delicious freikeh and their mansaf is really really good! Bon a petit :)
@Berlitz Language Center has certifications in Korean, Japanese, Mandarin and a few more languages in Asia. They are one of the best places to learn languages so i'd go with them if it were me. Good luck!
You can go to @InterContinental Hotel, you pay a 15 JD entry fee. Their food is very good but their drinks are over-priced and they pour according to hotel standards
