Park at Menara UOA accross the road. Its cheaper than the open car parks if you're parking for around 2 - 3 hours. Its underground so shaded from the rain and sun.
Quite convenient office area which has almost all ATM, San Francissco coffee, Secret Recipe, Hot & Roll, myNews, Level 3 Food Court, Riverside and few other small shops!
You don't need to go through the massive crowd at Jalan TAR or Masjid India to buy decent baju kurung at a very reasonable price - we have it here in Menara TM, LG1 - and the occasional flea market. N
I heard of stories from workers about some parts of the building which is reportedly haunted. Especially on higher floors. And this, is your friendly neighborhood Ghost Hunter :)
Parking issues never been solved in here. Basements are limited, VIP rate open air always full! If u have to park illegally outside, beware of the 'surat cinta'(s) by PDRM or DBKL.
