There is a mini-chain in northwest Indiana that I feel roadfoodies should know about. It's called Zel's Roast Beef, and while it is fast food, it is nothing like the abominable Arby's chain. Unlike Arby's, Zel's serves REAL roast beef sandwiches; you won't find any of that "chopped / flaked and formed" nonsense here. Great beef on quality bread - I get mine with a small cup of their delicious "juice" ( beef gravy ) on the side to pour over the sandwich. The crinkle-cut fries are of better-than-average quality, and there are a number of other sandwiches on the menu ( barbeque beef, burgers etc. ) My favorite Zel's location is on Indianapolis Blvd. ( US 41 ) at the north end of Schererville IN. Highly recommended by yerz truly.
