Thought bottle service in top nightclubs was off-limits to all but rappers, movie stars and others with entourages? There's a new app trying to change that.

Launching now in Los Angeles, BottlesTonight offers massive last-minute discounts on bottle service at hot venues all around town. It's currently in 11 local venues, including Couture, Create and The Sayers Club, and the creators say they're finalizing contracts with another dozen spots.

The app is essentially Hotel Tonight for nightlife: You log in (after noon; club managers are late risers) to see a list of clubs and the bottle-service deals on offer for the same day. The app advertises savings of up to 70 percent off menu prices, and there's a surprisingly extensive set of booze selections.

Right now (writing on a Thursday), you can snag a bottle of Ace of Spades Champagne at Couture for $605 – almost half-off the regular price of $1100 – or Remy Martin VSOP at Playhouse for $450 – discounted from $600. BottlesTonight guarantees that its prices are the same as or lower than any other promotion available.]

Another nice perk is that buying through BottlesTonight gets you a table and free cover for your whole group. And you can split your bill right in the app. (Everybody you're splitting with needs to download the app and log in via Facebook to do this, but still, better than trying to track down everyone's credit card at 2 in the morning.)

BottlesTonight debuted in San Francisco a few months ago, and its creators say it's seen 60 percent growth each month since then. And with the app set to launch in New York and Las Vegas next, it may well become an indispensable nightlife tool. (It's currently iPhone-only, but an Android version is coming next month, too.) Bobby Bottleservice would be proud.
