This week on The Main Course Patrick and Katy talk to Matthew Weingarten of Sodexo about the important (and admittedly difficult) process of improving the food in our institutions: schools, museums, stadiums, and more. Next Chris Parachini, owner of Roberta's, stops by to talk about the myriad of projects he and the Roberta's team have going on--including a burgeoning catering wing and a new slice joint in the works. Joshua Sharkey owner of Bark Hot Dogs talks about what good hot dogs are made of, what not-so-good hot dogs are made of, and why minimalism is key to a great dog. Finally Patrick and Katy set off a new series exploring the food scene in cities around the US; food critic Tim Carman talks to them about Chicago hot spots and the diner that Obama made a mecca.
