Broadway’s neon signs, racy rooms, and free-flowing champagne always stir your curiosity. But let’s face it: There are many other, less naughty places you’re looking to drop your dollar bills.

Like the sleek new Sugar Lounge, which just flicked on a hot pink sign in Hayes Valley. No, it’s not a strip club, but the owners aren’t afraid to bend the rules.

Gratis Asian nibbles line Sugar’s left wall after 5 p.m. nightly, while DJ Duane magically matches the genre you’re jonesin’ for. Lush purple love seats, weighty velvet curtains, and flickering candlelight complete the sultry mood.

Sink in with a sugar-rimmed specialty cocktail, like the Mangopolitan. Brimming with vodka, its splash of aphrodisiac mango makes naughty thoughts linger. Stay into the wee hours and you’ll be tempted to throw down a dollar for one of the scandalously good chocolate-covered strawberries.

Now that, sweetheart, is a buck well spent.

Sugar Lounge, 377 Hayes Street, at Gough Street (415-255-7144).
