The Middle Eastern food in this area is superb, and there are plenty of places on the tour to order a refreshing beverage and learn a bit about its history.
This tour is best started around 8pm. There are plenty of places to stop for food too, so don't head out on a full stomach.
Pickpocketing isn't unheard of, and watch bags or phones - motorcycles have been known to fly by and snatch them out of hands. Also, if you plan to drink it up, that's fine, but if you're the type who gets loud or pushy, watch yourself. It's normally very safe, but this is NOT the area to get into angry disagreements with locals. And if you happen into any of the girlie bars, DO NOT try and sneak a photo. You will be caught and thrown out on your ass.
