NEW YORK — Bringing your own bottle of wine to your favorite restaurant is getting cheaper and more popular.

With sales and traffic dwindling, many restaurants are either offering BYOB nights or chopping the "corkage" fee to open bottles bought elsewhere, to entice more wine-drinking diners to pay for a meal out.

"My fiancee and I are wine freaks, so we have been going to more BYOBs as a way to continue to drink great wine while not blowing our budget," said Christopher McGrath, a 26-year old money market trader and liability manager who lives in Montclair, N.J. — where BYOB restaurants thrive since state law restricts the number of liquor licenses available.

The signs that bringing your own is on the rise are still largely anecdotal. Christina Preiss, a 27-year-old Chicago resident, said wait times at her favorite haunts that let customers bring their own are on the rise. More restaurants are also advertising special BYOB nights and more aggressively promoting the fee cuts.

Bringing your own beverages isn't allowed everywhere — the rules vary depending on where you live.

But for eateries that can offer the option, it can be a way to boost traffic in tough economic times — especially for the fine-dining restaurants that have been hardest hit in recent months as even higher-income consumers cut back on pricey meals out.

Chris Cannon, owner of Manhattan restaurant Alto, decided at the end of last year to suspend a $60 corkage fee through September — a move he said has brought in more customers.

"Basically, we had to accept the fact that we were going through a recession," Cannon said.

Although some restaurants include information about their policies on their Web sites, most expect customers to call to find out whether they can bring their own. Some cities require a restaurant to have a liquor license while others do not. Even in areas where a liquor license is technically required, the rules are not always enforced.

Bringing your own bottle may not have the cachet of ordering off the list, where wines are sometimes paired with menu items to showcase the flavor of the food. But it can save you quite a bit of money. Restaurants frequently charge diners triple what they've paid for a wine. And they typically charge as much for one glass as they paid for the entire bottle.
