Looks like Mambo Cafe in Plaza Las Americas is gone and the whole mall closed until further notice: http://www.cancuncare.com/forum/viewtopic.php?p=502006#502006
Hopefully things will be back to normal soon! The news right now is all from the radio and gossip, so once there is more info I (or someone with the inside scoop) will let you guys know what's happening.
Dany told me this morning that part of Plaza Las Americas is open again. It's the southern part of the mall from Chedraui on down including the VIP movie theatres.
