Entering the nightlife fray without a picture of what's really available is like walking into a restaurant where they might decide you're too ugly to feed. Before heading out, get the dish at AllergicToLines.com. Started by three college students tired of velvet-rope abuse, ATL's a daily-updated roster of 30-40 venues and up to 40 partnered promoters, complete with the promoters' digits, emails, and the deals their complicated-denim prowess allows them to cut for you at the door. To get on a desired list, just text or email the appropriate promoter that you're showing up, and wait for confirmation; when you contact them, be sure to mention AllergicToLines.com, and hope he doesn't mistake you for a customer seeking his other business, addictedtolines.beeper. Each promoter has different deals with different venues: they all get you in with alacrity, but some offer comps before 1am, others get you reduced prices on bottles, and still others'll get your admission comped if you show up with two girls (just tell Mom you're taking her to that Queen Latifah movie). Of course more popular arrangements go fastest. Get involved too late, and you might get denied, but at least it won't be because you're too ugly. Even if it should be.
