Cocoro 668 North Wells Street (312) 943-2220 http://www.cocorosushi.com/ Mmmmm Shabu Shabu!!!!!   I have been a huge fan of Shabu Shabu since I was a kid after many visits with my dad and his Japanese partner.   I used to go to a place on Lawrence but that closed recently and we decided to celebrate my dad's 70th B-day at Cocoro.  The Sushi was very good but served a little bit too room temperature but it was fresh and very tasty.   We had Shabu Shabu for 5 people and it was really excellent and the staff was very helpful on setting up the hot water and helped cook and load the pot.  I am very happy to find another great place in Chicago for Shabu Shabu.
