It was a great EXPERIENCE; A day in shopping mall.

During my vacation last month, I had been to the biggest mall in south India with my family.
It was a great experience, as it's the leading shopping mall. However, the price of the items were heavy for a typical Indian. One best thing that I noticied, is the collection of fancy ornaments, because, the price of ornaments is really good as compared with other stores. overall experience had been memorable for me.
