Some guests had a super-sized surprise last week at Kung Fu Plaza in Las Vegas. Boxing great Roger Mayweather joined them, enjoying an authentic Thai restaurant in Las Vegas.

For those who don't know, Mayweather is a longtime and respected professional boxer who has won two major world titles in two different weight classes. He fought against scores of boxing champions in the 1980s and 1990s and is a well-known member of the Mayweather boxing family. Since 1996, he has trained Floyd Mayweather Jr. on and off throughout another great career.

Roger Mayweather was ready to watch last Saturday's fight.

Although the Mayweather family hails from Michigan, they aren't strangers to Las Vegas. Since so many of their fights have been held in the city for decades, they've become familiar with restaurants that are off the beaten path but still considered the best of the best. Kung Fu Plaza has been especially proud to have him as a regular patron for years.

"Roger Mayweather comes often enough that we don't make it a big deal very often. We love him, and consider him part of our extended family and want him to be comfortable while he is here," says Alan Wong, general manager of Kung Fu Plaza. "Last Wednesday though, it was hard not to be a bit more amped up about the fight between Pacquiao and Marquez. So we asked if Mayweather would take a picture with one of our staff. He agreed without hesitation. He is the real deal."

The Pacquiao vs. Marquez was considered a pivotal fight for the Mayweather family. The Mayweathers were especially interested to see how Pacquiao held up. He won, but not untouched.

"I watched the fight and wasn't sure if Pacquiao would win a major decision," says Wong. "And he left with 28 stitches over his right eye. So you have to ask yourself if Marquez could hold his own, maybe that is the right fight for Floyd Mayweather Jr. too."

Some people are still upset by the decision. One judge had scored the fight even. Two other judges gave it to Pacquiao.

The latest news on a Mayweather vs. Pacquiao fight.

Despite interest, the most recent reports say that negotiations for a potential megafight between welterweight champions Manny Pacquiao and Floyd Mayweather Jr. are over before they have even begun. Leonard Ellerbe and Richard Schaefer told ESPN.com that Pacquiao promoter Bob Arum was not interested. When Mayweather returns to the ring in May, it seems unlikely if not impossible that he will be fighting Pacquiao. Pacquiao is pursuing a fourth fight with Marquez instead.

While Roger Mayweather probably watched the fight, it was reported that Floyd Mayweather Jr. did not. He was making an appearance at a nightclub in Virginia. Floyd Mayweather Jr. is undefeated.

The Wong family thanks Roger Mayweather and family.

"We look forward to having Roger Mayweather and the Mayweather family back any time," says Wong. "He and his guests order different things, but one thing always remains the same. He enjoys the Thai fried chicken wings and we cannot thank him enough for honoring our restaurant."

Kung Fu Plaza is the oldest and most authentic Thai restaurant in Las Vegas. It was founded in 1973 after the Wong family moved to the United States from Thailand. The Wong family has gone to great lengths to preserve traditional Thai recipes. The restaurant also has one of the largest Las Vegas Thai delivery areas along The Strip.

Since Kung Fu Plaza has such a long history in Las Vegas, it is regularly frequented by celebrities and dignitaries from all over the world. It is especially popular among Thai people and those who visit Las Vegas frequently, such as professional boxers.
