Pizzeria for a group dinner

[jaba]

Hi all -
Hopefully this doesn't turn into a "best" deep dish debate, but I'm planning a group dinner for about 10-15 people (coming for a medical convention) and thought going to a classic Chicago pizza place would be fun.
From reading the boards, it looks as though Uno, Due, Pizano's, and Malnati's are good possibilities. We have people staying all over the Loop and River North, so any of these would probably be convenient.
Does anyone have any experience with or recommendations for planning an event at any of these locations?

Thanks!

Malnati's is a good bet. The one on Wells near Grand should work well location-wise. I've attended large group lunches there a couple of times.
