On weekend nights there's a velvet-rope cattle call split between Rush Street black pants and Ohioans with digital cameras swinging from their wrists.

Yet unlike Rush Street clubs, there's no booty shaking or obnoxious boozing going on at the Signature Lounge. The hushed, classic elegance of the leather-seated banquettes and green velvet mahogany trimmed chairs tames the rowdiest of revelers. The city skyline's tiny lights shimmer and the stars in the inky sky glimmer above, while the ghosts of screen stars like Jean Harlow and Clark Gable haunt from black and white movie stills lining the walls. Deco murals of the L and street scenes seem to undulate to the steady groove of bossa nova tunes on the sound system, while the diagonal lines of the familiar Hancock x-pattern trusses frame the plate-glass expanse of the room.

It's true that the drink prices, like the lounge itself, are high. The seasonal cocktails, like the $10.50 Green with Envy, a milky-green concoction of Vox Raspberry Vodka, Blue Curacao and mango puree, are excellent. If the heights don't get you dizzy, then the Top Floor Tea, $13.75, a boozy take on the Long Island ice tea filled with Chopin Vodka, Bacardi rum, Cuervo Tequila and Grand Marnier, will do the trick.

If all that drinking works up an appetite, there's always the teriyaki-glazed short rib kebabs or the oozy molten chocolate cake with banana emulsion and caramel gelato $8.50.

Average cost: $31+
