Harrington's Catering & Deli - Chicago
Established by Ray Harrington in 1951 and now run by his grandson, Ken, Harrington's is the best-known Irish caterers in Chicago. If you want their corned beef for an event any time in March, you'd better order it by the end of January.
Their Northwest Side deli serves corned-beef-and-cabbage dinners on Tuesdays and Saturdays all year round, though, as well as a daily menu of house-made soups sandwiches. It also stocks corned beef by the pound, Irish-style boiling bacon and other Irish specialty foods, gifts and Irish imports.
