A feature from Pokémon X and Y, and has been in the games since then. It's for people to trade each other good Pokémon at random, but most people trade Rattatas named something to the effect of "Cocklick".

Brock: Where is Pikachu?

Urban Trade is a relatively new retail clothing store, and I've only seen one of them in all my mall experience. They mainly sell Billabong, Quiksilver and the british brand Bench. Trying to find anything else there is near impossible. Not only is there a limited selection, but it is way expensive as well, and most things there can be bought at other places (even West 49) for a much better price. However, the store is very nicely layed out and very clean and tidy inside.
