The last thing UW-Madison needs at the end of State Street, where locally owned, diverse restaurants are available to suit all tastes and price ranges, is a mall food court. Sure, Sabarros is fine- but go to one of the two Ian's within 1-6 blocks away. Quiznos is Quiznos, but instead choose one of the 3 sub places on State Street instead where there are more options and more character. Against everything I believe in, I would even suggest Chin's over the stir fry places, if only because the atmosphere is less sterile and you can be involved in the energy of State Street.
The only appeal that I can see is that there is tons and tons of seating room and no one would ever bother you if you decided to stay and study for hours. For that, the large tables and giant windows are nice.
