LiDL

Sauber, frisches Obst aber oft überfüllt. Großer Parkplatz. Personal nett und arbeitet zügig

ein Lidl, wie alle anderen auch, nutze in manchmal weil er in direkter Büronähe liegt.

This Lidl is so great, in large part due to its proximity to just about nothing.
Granted, it’s located only a short walk away from the Neukölln station, but its presence is likely largely overshadowed by the much closer and more-​frequently visited Real in Neuköllner Tor. Additionally, the street it is on is more of a commercial or industrial area, with office buildings and such. This means that there are naturally not many people living in the vicinty, which means there is overall less traffic — foot or otherwise — here.
As a result, the feeling here is pervadingly calmer than in most Lidl locations. I have noticed that the employees are friendlier, the aisles are less cramped (with both people and items) and the shopping experience is much more enjoyable.
P. S. Another cool thing about this place is the gigantic parking lot.
