Oh! I forgot to tell you that it needs coupons to be redeemed. Where to get the coupons? Hmmm... Coupons are given away at all McD, 11am onwards with any purchase and at LRT, monorail stations. So, keep an eye look-out for those people wearing red and the mascot of a paper bag with Ronald McDonald's red shoes that might scare you sometimes. No worries, these are friendly teenagers giving out coupons.
Told you that they're friendly :)
