NEW ORLEANS -- Matassa's Market at Dauphine and St. Phillip was one of 5400 customers that lost power Friday afternoon in the French Quarter.

The corner grocery and grill limped along on battery power.

Cook Marcy Ramsey kept her sense of humor.

"I ride a bike most of the time, so I got my headlight on my chest, so I can see when I'm back there," Ramsey said. "I can do the grill and the fryer, but that's about it."

The bar at Port of Call on Esplanade remained open, but customers who traveled from near and far for the restaurants world famous gourmet hamburgers were out of luck.

No electricity and no gas, meant no food service there.

"We have no customers," Port of Call GM Mike Mollere said. "I'm just so sorry for everybody that I had to turn away, I guess about 200 people already. We're waiting on Entergy, that's all we can do."

One group from New York City, in town for a wedding, left Port of Call disappointed.

"It's crushing," visitor Nick Sinigaglia. "I came all the way down from New York to go to places like this and enjoy the outside and we can't really do anything right now. We're basically stuck in our hotel which doesn't have power either."

No power, no problem at B.B. King's Blues Club near the French Market.

The Kevin Gullage Band played unplugged and kept customers entertained. Gullage said in New Orleans, the show must go on even during a blackout.

"That's the funny thing about New Orleans you'll never find something that will stop us," Gullage said. "That's why we love what we do. This is music. This is our city. This is New Orleans."

Electricity or not, a table of customers from Lutcher said they enjoyed the show.

"I don't even see it being an inconvenience," customer Dennis Ledet said. "We still got alcohol. We got food. Who's inconvenienced? Not us."

Crews at Entergy's Claiborne sub-station on the edge of the Quarter, near Elysian Fields and the river worked to restore power.

The outage lasted about two hours.

The cause of the blackout is still under investigation.
