This is the central taxi for the whole of Munich. Very reliable. I prefer using this than phoning…read morethe number of the local taxi station points at kerbside - as drivers there sometimes fail to show up - but using this central number your call is logged and always handled professionally. Official taxis are more expensive than uber etc but regulation and safety is important to me. and these local companies pay taxes - which pays for roads etc . and are not owned (like uber is) by human rights abusing regimes like Saudi & Qatar, so i feel better. You can still pay cash and cards and probably other means in some. Stay local, support local businesses not abusive gig economy companies.
update 18.10.2019 because my caller id was not showing they dropped my call and didn't order the taxi while i looked up my number. that's bad service. i'm watching them - called back with caller ID on and everything ok. jeez p
