I wouldn't mind Tastee if they would maybe clean the place up, heck maybe even put the drive through on the correct side. Honest Abe's has onion rings that are eerily similar to Tastee's onion chips and that was really the only reason I ever risked going to Tastee.
I can't believe anyone eats food from that place. It looks hellish when you drive by. No way would I voluntarily go in there for food.
Certainly can't deny the place is in poor shape and would make many run-down shacks look good, but their Tastee burgers and onion chips and dip are well worth the heart clogging that ensues. Last I knew they are always closed Mondays, but that shouldn't be an issue for a weekend trip.
I try to make it there at least once every year or two when I'm back in town, and I've got a relative that requests frozen shipments whenever family visits them in Ohio.
I also suggest a Nebraska fast food stop at Runza. Even if you dislike their namesake runza, their burgers are probably the best I've had from a drive-through. And order some Frings (Fries+1-2 onion rings) as they are quite good as well.
