hey there. my dad's restaurant are kinda everywhere, just rmb the name and its coconut tree logo!
and to narutiment - shopping wise. for teenagers i would recommend a few. there are brands which prices around topman's. its called izzue, and also chocoolate. their stuffs are pretty cool. other than that, theres a very small mall in mongkok. its called 潮流特区。 but i would say try to avoid going on weekends. its gonna be super duper packed and the mall is really tiny. heh, good things in hk are usually not recorded in those travel books. cept for common places. 'the peak' has good views, i think its worth going. well, im very much living in sg so not exactly very good in recommending. i only go back every december. let me check with my sis then i might try to post more worth-going places!
