One of the shops that I found really interesting was Lampu.kl, because it was essentially a showroom with no staff. The shop sells customized neon lights, and there are a couple of setups within where visitors are encouraged to take selfies with. Next to the neon signs are QR codes that you can scan for more info on the pieces, as well as the price. Of course, you can find their social media handles on the posters around the room. Maybe this is the future of shopping.
There are quite a few cutesy shops selling handcrafted items and kedai makan (geddit?) here. We bought some essential oil from Wunderbath, pillow from Corak and Pattern and checked out Mossy Bola Kedoma.
