As I was with my wife I managed to get to see the outside of most shops but didn't see much inside. Most of the card shops only had a small MtG section but I found one called Big Magic

And it had a fair amount of cards all arranged in display cases


There was a rack of booster scans so I figured you just took it to the desk and they picked one from out the back

One cabinet stood out





Big Magic looked to have a small area to play but none of the others did and these places were packed!
Never seen anything like it before. In England we just had a couple of albums or the really good ones were in the shop counter display. Hong Kong had a deal where you went up to the front counter and told them what you wanted and then someone out the back would bring it to the counter.
Hopefully I can go again but the wife really didn't like the area at all so it is looking unlikely :(
