Classy nightlife in Manchester

Hey guys and girls.

So I'm 34, and I've spent the last half a decade or so living in one of the largest cosmopolitan cities in the world.

I'm now in Manchester and struggling to find anything resembling a classy night out.

Looking for cocktail bars that are spacious and invite numbers but not over crowding and availability for mingling without having to hug.(as I experienced with Rio de Cuba)

Places where, wearing a £1,000 suit is ok and you don't have to worry about drunken kids sloshing pints around.

Where people are happy being sober(ish)while drinking and talking.

Basically, places with class.

Hope someone knows some Where ^^

Thanks in advance. Leigh
