Restaurant city

i used to like Sims for a while, then Diner Dash (still love it).
and i recently 'discovered' that this game on facebook is actually quite fun :$
started playing this Restaurant City just few days ago... have been ignoring all the invitations i got from my facebook friends for so long.
was quite excited when i found out that by picking up rubbish in my own restaurant and other friends' restaurants can earn me a award/trophy. :$
then i got even more excited when i realise that by clicking on some of the trees nearby can earn me money!! woohoo!! XD
