New to Tbilisi

Hi all, over the coming 2 months I'll be visiting Tbilisi every week a couple of days for a work project. Would love to hear some suggestions for things to do and places to see in the city.

First question: does anyone know a good English speaking driver whose services I can use while in town? Thanks.

Looking forward to get to know Tbilisi and Georgia a little better, and possibly meeting with some of you over the coming weeks!
