Ive been a pizza fanatic for years, I know everything there is to know about it, Do you like pizza? 
I love pizza especially Chicago style deep dish.
Me too!! Id say deep dish pizzas from Chicago are the most famous known deep-dish pizza.s out there. Dont you agree? 
I do, too.  I can't remember if Lou Malnati or another kind is the most famous in Chicago.
Oh yes! Lou Malnati's Pizzeria, Ive been there before, Its a great Chicago-style pizza restaurant, I believe its in Northbrook, Illinois.
Oh, didn't realize it was in Northbrook.  Do you know when his pizza originated?
I believe Lou Malnati started working with his father Rudy way back in the 1940s making deep-dish pizza's.
Wow, that's a long time!
It sure is! I think they have several chains of pizzerias around Illinois but I'm not too sure. Although there are a ton of pizza chains in that area that ive been too. 
What other chains?
