Greenhills is your go-to place for all your gifting needs on your trip. You can find hundreds of thousands of high-end knock-offs as well as original merchandise at the fleamarket-like stalls and shops on the floor. There are several levels as befits any typical mall where you can find places to eat, sit, and shop. You could spend an entire day here and not even scratch the surface of all that this mall has to offer. You can find items for yourself, from jewellry, to clothing (at most they cater to a L/XL), belts, watches, trinkets, shoes, and they even have a huge section just dedicated to cellphone accessories (phone covers, screens, chargers, etc). I particularly enjoyed their art offerings available, of which you could buy prints, copies, and some original art as well. Definitely a must-do on your trip. And make sure to dedicate an entire day (prepare a list of names for gifts beforehand and make sure you have enough cash on hand). Be wary of pickpockets but keeping cash on your body. Do not take your handbag unless you can keep it close under your arm. I never felt unsafe at any time because I was overly-vigilant, but I was warned by locals. And always barter on price. Don't just buy an item from the first stall you see, further down in your discoveries you will find other stalls with the same products, possibly at a better price. Else pit them against one another. This isn't India though, so bargening may not get you too far.
