Said restaurant owner made claim that a beef is just way too expensive for the average college student. I tend to agree with him out of common sense.
i'm not sure i'm following you. most italian beef sandwiches run $3-$4.50, which is the same as you'd expect to pay for a decent burger. it's not an expensive item.
portillo's website lists a beef sandwich at $4.09, and a combo at $4.69. a burger is $3.09 ($4.39 for a double) and cheese is extra. not a big difference.
not as cheap as hot dogs, of course.
oh, and it's not hard to make a decent beef/sausage/combo sandwich. it's just a matter of sourcing good product. you should be able to buy scala's beef and juice frozen through major suppliers in indiana.
beef sandwiches are a nice and easy pickup for a place with limited space as well, because all you really need to do is heat the juice, hold it in a steam table, and dump a bunch of sliced beef into it every now and again. to serve it, it's just a matter of putting it onto the bread, dipping, and adding peppers.
and i think there are enough kids at IU who originate from chicago, that they'd appreciate a decent beef sandwich.
just my $.02.
