Uber's experiments with food delivery in California and Spain must've been a resounding success, as the ridesharing outfit is making that on-demand dining a permanent option. UberEats has officially launched in four cities, including the Barcelona and Los Angeles trial areas as well as two new burgs, Chicago and New York City. As before, the service really just substitutes pickups for meals -- you choose from curated restaurant menus, and an Uber driver will show up with your selections in a matter of minutes. This will seem very familiar if you've tried a restaurant delivery service before, but it'll undoubtedly be handy if you already use Uber and find yourself craving sandwiches or salads.
