They all have their ups and downs....
Magic city is deep downtown(government district) so that area clears out big time at night. The girls are not as personable due to all the hype (unless you come off as 'money' or are a known personality)...and there is not ultra private VIP (if thats your thing). They don't seem to flirt too much (not even as much as the 'fake interested vibe/small talk you would get at a Hooters or Twin peaks). There is not a lot of body to body contact either (if at all/mostly table dances). That's the main reason I stopped going there. But I do know for a fact that they look for the 'cream of the crop' looking women (subjective of course). I had a friend with an awesome body who dances and they told her that she still needed to "tighten up" and she hit the gym for months before they would take her. There is usually no day staff and its probably more dead during the week
Onyx is more in buckhead so it gets a mix of business people from nearby hotels and lower end townsfolk at the same time but its also pretty random during the week vs the weekend
Blue Flame is in the hardcore hood (historical bankhead area on a side street off a main highway). This place feels shady as hell the moment you walk in. The girls are super-urban for the most part (tats for days, big thigh, big asses, broken english -- a few cuties but more rugged for the most part) I know the name appears in a lot of hip hop songs but I would argue that those guys don't even step foot in there anymore. It's REALLY shady. I think they're open day times if you want to scope it out before night falls....could be more relaxed then.
Babes is somewhat of a hidden gem but its in an industrial/trucker part of the city right off the highway. But I can say that the crowd is pretty cool and its a chill place. Nice day staff of ladies working (especially towards the end of the week) and you'll get a wide mix of patrons there during the day (ie not shady). Night time does get a little crowded and shady and it can get damn near body-to-body crowded on weekend nights (real late). They're undergoing a renovation so the club does look a little nicer. Also, they have a hip hop legend of yesteryear that usually DJ's there (MC Shan) and they have sports parties and boxing events etc (although I've never been to one). Quite a few cuties and the majority are extremely friendly and really personable. Dances are only 5 bucks here too
Club Wax: This one is across the highway from babes....stay away from that one like the plague...feels really dangerous and third world in there. If that's your scene - have at it -- otherwise no.
OTHER TO CONSIDER
Follies: Nice mix of black, white, and other and quite possibly the most popular option in town right now. There are always more than enough black girls dancing if thats what you're looking for (around 8-12 on any given day). Gets major crowded at night -- really fun during the daytimes -- especially towards the end of the week.
I know theres a few more out there for black chicks but I don't know about them
