Night Market (Not far from McDonald's on a side street). around 18:00-midnight. A night market with numerous stalls selling all types of handicrafts, jewellery, art and presents. Most vendors enjoy bargaining with you and will accept a lower price than they first offer. Prices are not cheap compared to other places in Thailand but they are cheap compared to other places in Lamai.
Tesco Lotus. There is a small mall before entering the supermarket with many shops selling clothes, beauty products and electronics and also some restaurants including KFC, Sydneys Fish and Chips and Black Canyon Coffee. Tesco Lotus itself has some clothes at cheap prices and food which is price marked, great if you are self catering.
Walking Street. Every Sunday, Lamai Beach Rd between the market and the bridge is host to walking street. The whole of the street is closed off to traffic and is full of stalls selling clothes, handicrafts and food. The area is full of Thai people when the market is on so prices are cheap and the food is fantastic.
