Well basically as of writing the electronics mall is being demolished but only the metro city is left. One thing notable for me is the Starbucks on the second floor with the patio(has a great view of the intersection). There are also a handful of good restaurants here.
However if you are on the hunt for electronics. Go exit 9. Once you go out all buildings on the left are electronics store. You can get items which are less than than market prices if you know how to haggle
