Bourne & Hollingsworth Bar

This basement bar ain't easy to find, but that's kind of the point. This place has recently had a revamp, and a new lick of paint is an understatement - think less of the old Grandma chic style, and more vibrant colours, with mismatched boho-style patterns – there’s a lot going on. The cocktails are wild, with flamboyant takes on the classics. The Stout Old Fashioned is a bit of us. A few of these and you might finally pluck up the courage to ask your boss for a raise.

Sing Easy at Piano Works 

Karaoke is fun, but when it comes to belting out the high notes of All I Want For Christmas, we prefer to leave it to the professionals.  Most of the time.

Your colleagues will just be spared the addition of a microphone.
