Crystal,
My vote is City Lobster. They have great lunch specials, it's a very relaxed atmosphere, and has a nice selection of tap beer (if he likes that). It just seems more fitting for a college student. Blue Fin is more of a business atmosphere.
There's also Ruby Foo's (49th and Broadway), Asian-Fusian/American and it too is very reasonable. Same owner as Blue Fin (Steve Hanson). Food is reliable, good, and generous portions.
I hope Harrison enjoys his excursion! Lucky boy to have Mom's cc
, & the heat should be breaking by Thursday!
