The coffee quality is good. It has got an authentic taste which energizes you after the tiring shopping. But be careful at the billing, the stall will cheat you. It happened with me. I paid him with 6 sodexo coupons, he skillfully dropped one coupon in his cash drawer and said I paid him less.
I had no option to prove so had to pay him the extra bucks to avoid creating a scene. Especially when i was visiting with family and small children.
