A shopping temple for which you need a lot of time to discover everything. One of the few stores where there are always enough employees to take care of customers. Personally, I note that in "Karls Kitchen" the dishes are noted on blackboards that the visually impaired like me cannot read. Maybe you have a better idea (e.g. blackboard closer to the guest or write larger or not lined up so closely together)
