This is the entrance to the famous ‘Fake Market’. Don’t get aggravated with all the touts, have fun with them instead. Ask them crazy questions like to prove how big the suitcase is by getting in it.
When bargaining they can start a bit high. Aim for 40 - 60 for T-Shirts and longsleeves, never more than 50 for a watch or 300 for a leather bag. Good luck, lots of bargains and the quality is decent.
