thank you for your quick reply, I must admit I am a bit reluctant, because there are no housenumbers in this area in OpenStreetMap and here https://www.openstreetmap.org/note/2082343 there is a note that seems to conflict with the restaurant being "just to the left" of where you added it. Do you recall if the restaurant was deep inside the block like the marker, or whether it was close to the street? My guess is we'll have to resurvey this because GPS reception can play funny games in dense urban areas.
