UberX drivers will deliver a $10 bowl of pasta from Porano Pasta, a Gerard Craft restaurant about to open downtown, on Wednesday. 

The new eatery will be a fast-casual concept at the Mercantile Exchange. It will draw on the food served at Craft's Clayton restaurant Pastaria and follow what he calls the "Chipotle format," he told the Post-Dispatch last year.

Craft will deliver some of the food Wednesday himself, Uber said.

Request UberCHEF on the Uber app in St. Louis from 11 a.m. to 1 p.m. and tap "request pasta." 

UberX is an app-based ride-hailing service in which drivers use their own cars to ferry passengers.

It has operated in St. Louis and St. Louis County since Sept. 18 in defiance of St. Louis Metropolitan Taxicab Commission regulations that mandate drivers undergo fingerprint-based background checks and possess a Class E Missouri commercial drivers license, also known as a chauffeur’s license.

Those requirements are mandated by Missouri law, the commission said, but Uber described them as onerous. Uber says it conducts its own thorough background checks of drivers, but not fingerprint checks.

The two sides are embroiled in lawsuits against each other.

It's not the first time Uber has expanded its services from giving rides.

On Oct. 29, the company delivered kittens for 15 minutes of playtime for $30.

About a month later, Uber users could summon a car with a venture capitalist in the back seat listening to business ideas.
