i attended a party recently at the manila polo club. i don't know if it was just a hot day or their aircon was not working well, but it was warm inside the main ballroom. when you're looking for a venue make sure to ask if their aircons are working. it gets a little warm specially when there are a lot of guests.
and i forgot, to mention about their catering service. i think its inhouse, just forgot the caterer's name. their waiters are hard to find and they are a little slow in replenishing the food in the buffet. but the food was not bad.
