In the post-Soviet era, there are some pieces of modernization they seem to be bypassing, while throwing weight behind others.
culinarybackstreets.com and roadsandkingdoms.com are the sites on which I've been reading that stuff, plus after that, googled some more for Georgian food blogs, etc.
It is just a charming old city with cobble stoned streets, a river running through, between hills, with a funicular (cable car) running up to the fort and the "Mother of Georgia" looking down ([1], similar to Christ the Redeemer in Rio).
Excellent food and wine and brandy, cool bars (41 gradus), decent weather, inexpensive, many historical sights, long history, native script, much friendly, very hospitable, wow.
