There is something inherently warm and inviting when you roll-in/step inside. Perhaps it is aroma of freshly roasted coffee and/or hazelnuts, feel of wooden floor or chat of local version of ancient chorus of oldtimers. Most certainly, you are invited to mingle. Hence the local name, Minglement.
For someone with mobility issues, the main floor (incl. barrista station, front counter, tables, snacks, packaged coffee (their own), tea jars (lower rows only, unless your wheelchair has a lift function)) is fairly accessible from the main entrance and navigable inside. The staff is very friendly and is ready to help you carry your cups or plates to the table. All of the condiments and coffee paraphernalia are located on a high table and out of reach for most non-lift enabled wheelchair customers.
It is all great until you need to use toilette which is located in a separate part of the building accessible only via stairs. Similarly you are out of luck if you want to shop for organic groceries, supplements, clothes, books, etc.
Lack of accessible parking (for vans with side ramps) could be an issue on summer and holiday weekends when the place is packed with tourists. I usually park in front or next door where there is enough place to fold out the ramp.
