I know too that I'm posting late, but some other decent restaurants that aren't too far from 90/94 that you could've gone to include Tre Kronor, Edelweiss, Mirabell, or Guey Lon! At least, on the other hand, someone was smart enough to suggest Sabatino's(which I feared noone would mention).
Anyway, Tre Kronor is a very good restaurant to eat at. It isn't so close to 90/94 as Sabatino's is, but it's just as upscale as Sabatino's, and you won't have to drive excessively far east, as you would with some of those other suggestions I've seen(i.e. Khan, Hopleaf, etc., and no offense to those places, since I like them just as much as anyone else). It's in the same 2-3 mile distance range away from the expressway, just like Laschet's is(or its rival, Resi's Bieustube). Anyway, Tre Kronor is a Swedish restaurant that goes beyond just your basic Chicago Swedish diners(i.e. Ann Sather, Svea, etc.), and even puts them to shame. Excellent entrees, traditional Swedish entrees(i.e. Salmon Dill Quiche, Swede. meatballs, etc.), and delicious pastries. The servers will usually give anyone dining here samples of appetizers on their menu(such as tuna squares, which I recall having once here), which is a great touch to the ambiance of this place. Also, if you're on your way to neighborhoods to the east of here(such as Andersonville or Uptown), it's located at a nice halfway point inbetween the Kennedy(90/94) Expressway), and lakefront neighborhoods such as Andersonville.
Edelweiss and Mirabell are both German restaurants not too far away from the expressway at all. Mirabell is located just across the street from a KMart, and immediately to the east of the Kennedy off of Addison Ave. Edelweiss is on Irving Park Rd., and not very far east of O'Hare airport at all. It's located just to the west of both Harlem-Irving Plaza(aka the 'HIP'), and the Rolling Stones music store(not to mention, Rolling Stones would make a nice stop, after a good meal at Edelweiss, since I believe it's open every night until midnight).
Finally, Guey Lon is a decent Chinese restaurant that's operated in Chicago for about 50 years, located on Elston Ave., just to the south of Irving Park Rd. They also serve certain Thai dishes too(such as Pad Thai), and are well known for their food, due to the fact they've participated in the Taste of Chicago for many years.
