First of all, I freely admit that I am a huge Papa Del's fan.  However, I'm always in search of other great Chicago-style pizza in the Chambana area as well, so I decided to give Rosati's a try after reading some decent reviews and seeing a few pictures of their deep-dish pizzas online.  Unfortunately, my Rosati's experience was mostly disappointing.  \n\nFirst, my friend and I arrived at the restaurant and ordered a medium deep dish pizza and two drinks for dine in (about $20 in total).  We were then given cheap Styrofoam cups, paper/plastic plates, and plastic utensils.  I'm sorry, but if Rosati's is going to offer a dine in service, they should at least provide better quality utensils, glasses, plates, etc. (especially since deep dish pizza is very messy and can be hard to cut- even with proper silverwear).\n\nAbout 40 minutes later, our pizza was brought out to our table.  The wait time wasn't really an issue- I'm used to that from Papa Del's.  Great Chicago style pizza takes time to make... unfortunately the pizza we received from Rosati's was less than great.  In fact, it was probably the greasiest pizza I have ever attempted to eat.  Also, the cheese and sauce both had an artificial taste (reminded me a bit of Pizza Hut- aka far from 'natural'-tasting ingredients).  The best thing the pizza had going for it was the crust- which was comparable to Papa Del's and traditional Chicago-style pizza in general.  However, that wasn't enough to save it from the grease overload and artificial taste that made my friend and I give up after eating one piece each.\n\nSo yeah, Rosati's was not for me.  If you decide to give it a try, I wouldn't recommend dining in due to the poor quality utensils (though the dining environment itself is alright).  When it comes to the pizza itself, expect A LOT of grease and a taste that doesn't quite match real Chicago-style pizza (though the crust is close).
