Suntec City has re-opened for business and I find accessing the East Wing (via Promenade MRT) to be much easier than entering via the West Wing (via Raffles City MRT and walking through Citylink).
Brand new Prize Stage Arcade, super sized space.
I bought pastries from Marche to bring home, their bread selection is very popular but I am not a bread person. Muffins and coffee from Jamaica Blue for my mid-afternoon teabreak, the berries used are really fresh and wholesome.
There is a specialty piano shop, cigar shop and even Brick World (lego). Keep walking through B1 or L2 and you will reach Citylink.
