Casa Sanchez first offered the promotion ten years ago and has now brought it back, calling it the "stimulus special," said owner Marty Sanchez, who first spoke to ABC News affiliate KGO-TV.
Sanchez told ABCNews.com that customers who get the logo tattoo, which was modeled after his little brother, Jimmy, are entitled to one free meal -- customers have their choice of burritos, tacos, tamales and more -- and one free drink per day.
"People always said it was a cute little logo and it would make a great tattoo, so we decided to see who would really be interested in making a tattoo," she said. "And we thought if the tatoo's for life, then it's only fair to give them free lunch for life."
Customers, she said, must pay for the tattoos themselves. The tattoos typically cost about $100 to $140, so it takes a Casa Sanchez patron about 12 meals before he or she breaks even on their investment, Sanchez said.
A decade ago, some 50 customers took part in the promotion. This time around, she said, three more have gone under the needle so far.
Sanchez isn't worried, she said, about throngs of tattooed patrons consuming enough food to drive the restaurant into the red.
"Nobody can eat the same thing every day," she said. "I grew up in the restaurant and I can't eat the same food every day."
Las Vegas still has plenty of sin to go around; at least that's what the city's marketers would like consumers to think.
An ad campaign by Las Vegas Tourism revamped its old slogan "What Happens Here, Stays Here," and attempted to refute claims that nobody is interested in all that Sin City offers.
"All of the news coverage made it sound like things were closing down and we were boarding up the town, and that's clearly not the case," said Betsy Ward, the director of communications for R&R Partners, the firm handling Las Vegas' advertising.
"We had to show, in a dramatic way, that regular people are coming here and having a blast," she said.
And dramatic it was.
The ad depicted faux television reporter Candace Newman delivering the news on the dismal reality of life in Las Vegas: Empty cabanas and pools where "the water's warm, but nobody's getting in."
But as soon as her broadcast ended, Newman stripped down to a skimpy bikini and joined the revelers in the nearby pool.
"We decided to push back a little on the message that the sky is falling," Ward said. "Yes, things are tough but people still need a break and Las Vegas is the perfect place to do it."
Air New Zealand staff members are baring it all -- for the sake of business, of course -- and they're not at all shy about doing it.
In an ad released last year, Air New Zealand painted 80 of its staff members in body paint, eight of whom were wearing no clothes at all, in an effort to prove to customers that the airline is serious about not hiding anything.
The airline was promoting its "no-hidden-fees policy" that it hopes will boost business.
As for the issue of nudity, the ad's creators strategically placed beverage carts and luggage in the way of the staff's most private parts.
