WASHINGTON — Hey, sometimes at 1:35 in the morning you just need a bag of Funyuns, a DVD of Adam Sandler's "Big Daddy" and four rolls of Charmin.

That's when a guy named Vinnie pedals to the rescue.

Elvin "Vinnie" Martinez is one of a few dozen bike "riders" for DCSnacks.com. It's part 7-Eleven, part CVS, part Blockbuster, which is altogether fitting for these impatient, broadband-connected, junk-food-addicted times. Forget stores. Who wants to stand in line when you can watch Tony have a tiff with Carmela as you wait for your pint of Haagen-Dazs to land on your doorstep?

For many George Washington University students such as Patrice Louis, DCSnacks is as basic part of campus life.

"This is just the most convenient way to pig out, man," says Louis, 19, whose favorite is Haagen-Dazs vanilla.

A lobbyist is craving garlic-flavored bagel chips. It's 10:40 p.m. Tuesday. No problem.

Three roommates want six pints of Ben & Jerry's. It's 12:15 a.m. Sunday. Solved.

If you live within a mile of the White House, you can log on, order with your credit card and wait about 20 minutes for delivery, seven days a week, starting at 8 p.m. and staying open on some nights as late as 4 a.m.

Matthew Mandell is the 24-year-old beefy, restless and excitable entrepreneur who came up with the idea. With a borrowed laptop and about $1,000 in capital, Mandell kicked off his venture in January 2003, when he was a junior studying psychology at George Washington (he graduated in 2004). The business grew.

Three years ago, he sold fewer than 50 items. These days, he's up to more than 800: 31 flavors of Ben & Jerry's, 11 kinds of Vitamin Water, at least a dozen types of cigarettes and tobacco, Nyquil, Immodium and Monistat, Lean Cuisine cheese ravioli and Hot Pockets ham and cheese, DVDs of Ice Cube's "Friday" and Diane Keaton's "Something's Gotta Give," condoms, etc. Mandell makes his money off the products; delivery is free.

For two years, Rashid al-Khalifa has ordered almost every night — chicken pot pie, Gatorade, lasagna, whatever. He often has guests in his apartment, and a man's got to play host. The 23-year-old George Washington sociology student lives on a second floor, and the rider has to toss the order up to him. "That's personal service, you know what I'm saying?" he says.

Four months ago, Mandell changed his business's name from Campus Snacks to DCSnacks and came up with a new slogan: "Fresh Snacks for a Hungry City." He has about 50 people on his payroll, most of them George Washington students. Mandell pays his mostly male staff $7.50 to $15 an hour, depending on their duties.

He has been a consultant for a business similar to DCSnacks at Columbia University and is "in talks" with "a certain college in Boston" to serve as a consultant there, too. But don't ask Mandell how much money he's pulling down. "Revenue? What's our revenue? That's how much money we make," he deadpans, though he's making enough to rent a one-bedroom apartment in the city and drive a Lexus 330RX (which he makes deliveries in).

The U.S. Business Directory estimates his company's sales at $1 million to $2.4 million. Says Mandell, "That's not completely correct, but not that far off. Let me just say we serve hundreds of customers a night."
