WHEN Barack Obama does the mundane it’s not boring, it’s an event.

The former US President received a rock star welcome when he stopped at a restaurant for a quick bite.

His craving: a taco. His choice: Coyo Taco restaurant in Miami.

Obama had stopped for a bite with Andrew Gillum, the Democratic candidate for governor of Florida, and Democratic Senator Bill Nelson after a rally in Florida on Friday.

“I want everybody to vote!” he urged supporters, as surprised diners looked on in amazement and cheered at seeing what many consider America’s coolest president ever.

Obama even posed for selfies complete with a tortilla chip and guacamole in hand.

David Smiley, a political reporter for the Miami Herald, said women dining on the patio screamed when he popped out of a silver Chevrolet Suburban.

“They grabbed their cell phones and shot video. And then they called their friends,” Smiley said.

One diner even got a hug from the 57-year-old after she told him she was there for her bachelorette party.

Smiley posted a picture of a receipt of Obama’s order on which his name is incorrectly spelt “Barrack”.

The receipt shows Obama ordered a Cochinita Pibil, Pollo al Carbon, Camaron, Guacamole and Esquite for himself and treated Gillum to a bottle of Coke.

Kali Hughes, who took Obama’s order, said he left a $40 tip, the Miami Herald reporter says.

Everyone got so caught up in the excitement that Obama was left wondering what happened to his order.

“Where’s my taco?” he was heard saying.

“Everybody was busy taking all these pictures.”

Obama is taking on an increasingly prominent role in the final weekend of campaigning before midterm elections in which Republican control of Congress is threatened.

At Friday’s Florida rally he told voters that only his party would defend the 2010 healthcare law that was his signature domestic achievement.

The still-energetic but visibly greying former president also warned against the politics of fear and criticised dishonesty in campaigning — comments directed at Trump though Obama did not name him.

He is set to flex his political muscle again today in his hometown of Chicago, as well as in Indiana, where the seat of Democratic Senator Joe Donnelly is in danger.
