Vegan cafe owners grilled by horrified diner after their children ran amok during meal.

Owners of a vegan cafe in the United States have been grilled online for letting their “naked”, “dirty”, “yodelling” children run amok amongst the diners.

In a now-viral Google review posted last week, patron Chelsea Bartley said her recent experience at Infinity Vegan Cafe in Memphis, Tennessee, left her feeling bewildered and “uncomfortable”.

“During my visit, a bare butt naked baby was running around, stood up on a table with its [dirty, black] feet, and bent over to show me it’s butt hole. I wish I was exaggerating,” she wrote. “An older kid came over and started like yodelling and staring at me during my meal. I was SO uncomfortable.

“Like, I get it’s a family establishment and kids do weird things, but [the] naked baby was running around for like 15 minutes while all the workers are just standing to the side talking and laughing over it.”

Bartley wasn’t overly fond of the food either, declaring she could “heat up a tofurkey sausage just as well and in under half the time.”

She gave the cafe two stars.

The complaint not only attracted plenty of attention on social and traditional media, but also a visit from the county health inspector, who according to WMC Action News 5, didn't find a single violation.

In a good-humoured Facebook post after the event, Infinity owners Adam and Kristie Jeffrey defended their impeccable food safety score and their little ones' antics.

"Clearly our 22 month old isn't familiar with the 'no shirt, no diapers, no shoes, no service' policy and we're working on that," the couple wrote over the weekend. "She has always and will always be under close supervision and further 'rip and run' escapades are being closely monitored.

"However, we have an open door singing policy and encourage and foster our kid's love of music, so be aware you could be serenaded at any time!"

While the Jeffreys said they were forced to temporarily deactivate Infinity's Facebook page due to "unnecessary cruelty of some commenters", the whole saga has also earned them plenty of support and given them plenty of laughs.

"Through it all our love for our children, and the importance of making them a priority over profits, has not wavered," they wrote. "We encourage our children to sing, to play and to love life. We are blessed to be able to include our children in our day to day lives, and wouldn’t change it for the world."

They've promised that "#buttholegate" T-shirts will be available soon.
