Urban Vegan. Their delivery area is between Addison and Foster, so we're right in their wheelhouse. The phone number is (773) 327-9200.
They open at 11am daily. You can find out more about ORD on their Facebook page and see their menu on their website. A link to a PDF version of the menu is here.
If you do call for delivery -- at ORD and elsewhere -- be sure to be extra generous when tipping the delivery person during this dangerous cold spell.
