Have been to the Mahane Yehuda market several years ago and visited around noon on a Friday. Market was mobbed but for a lot less than $100 per couple, my wife and I sampled whatever looked good to us including freshly baked challah, some pastries, cheeses and some freshly squeezed pomegranate juice. Most every vendor speaks English so communication is not a problem, If you are unable to get a group together, don't hesitate to do it on your own. Although prices are in shekels, many of the vendors are happy to accept dollars. This experience is not to be missed; with or without a guide.
