Sometimes they're early, sometimes they're a bit overly talky, sometimes they have to get their sat…read morenavs out (at least they have them!), but overall, New City, my nearest taxi company when I lived in South Manchester, are downright fab. I still use them when I to and fro there for various reasons.
We've used them countless times since moving to the suburbs, and they've not let us down. In fact my visiting friends asked one of the drivers for a curry house recommendation in Rusholme and he was only happy to oblige... and it was one of the nicest curries we've ever had. Plus there's one driver who always takes me to SafeStore and is as friendly as they come - last time he even showed me some pictures of his lovely family on his phone (while keeping his eyes on the road, obvs... I'm not daft) and asked me about my driving lessons. He even helps carry my ridiculous volume of boxes to and fro. He's a keeper.
If that doesn't make them a good cab company, then nothing else will!
Note: There is however one driver that I've since nicknamed as having The Deathcar. That guy scorches over speedbumps like some kind of demon. Kinda smells like booze too. Meh, it's an adventure...?
