Update: my coupon is invalid for some reason. It seems to me they deleted their franchise from Lieferando a few days ago (or it was deleted?) and registered it with Lieferando anew, so now my coupon is invalid, because it was for the past reiteration and not the new one.
I guess, they're scammers or something that want their restaurant to be shown at the top, because allegedly it's "new" or they had some bad reviews? I don't know, but sucks that my coupon is invalid now, so I won't order there.
