Sup Alex! Here's the deal, bro. The smoking law is that you can't smoke inside any restaurant/bar that allows children. Most with patios allow you to smoke outdoors at your table. Some restaurants stopped allowing kids so they could continue to allow their patrons to smoke, while others allow smoking after 10pm. Titty bars allow smoking in them. As for restaurants, the Vortex is very good. Nice beer selection, nice Scotch selection, and no kids allowed, so you can smoke til your heart's content. Great burgers too. Check out the Brick Store Pub in Decatur also. They have an absolutely ridiculous selection. According to beeradvocate.com, it's ranked the #2 beer bar in the world. For jazz or blues bars, there's the Apache Cafe, Sambuca(non-smoking), Blind Willie's, Churchill Grounds and the Northside Tavern. The big two microbreweries are Atlanta Brewing Co. and Sweetwater Brewing Co. Both are located in midtown Atlanta so they're not far from the Georgia World Congress Center.
While at the Brick Store Pub, you can take a trip over to Puff n Stuff and check out Al.
Here's a few cigar bars:
Highland Cigar Co. (No food, decent liquor selection, below average beer selection)
Buckhead Cigar Co. (Good food, good beer and liquor selection, no music, kinda small.)
Beluga Piano bar (Night club. Good time. No food. Good liquor selection, mediocre beer selection)
Chops Lobster Bar (This is one of the best steak houses in Atlanta, so the food is excellent. Excellent liquor selection, good beer selection)
Keep me posted on this so I can catch up with you.
