Which official LEGO stores have the largest selection of bricks in their PAB wall? Official LEGO stores offer the opportunity to fill a cup (small or large) with LEGO elements from a wall with shelves, usually near the back at the store.
These are called PAB walls (Pick A Brick)
This is often one of the cheapest ways to purchase LEGO elements.
However, the size of the wall and hence the size of the selection, differs from store to store.
I was wondering, which stores have the largest wall ?  In Europe I think it is the one at Disneyland Paris, but I could be mistaken. I'm also interested in other countries/continents...
I cannot seem to find the official press release for Berlin flagship store re-opening in 2017, however various sources1, 2 state at that time it had the Europe’s largest ”Pick &amp; Build“ wall. Latest news I could find related to this particular shop wall is couple of months old (in German). There's a picture representing all parts available for PAB with 144 parts/bins.
I've also found following picture on Imgur via Reddit post, showing the size of PAB wall
