The reviews already posted expecting cleanliness from a cross between a diner & a McDonald's are kind of funny. You come to Steak 'n Shake for grease or cheap, and they deliver on both fronts.
Sadly the portions on fries & side salads have gone really down over the years.
One super plus if you have kids is that they eat free with an adult meal purchase on Saturday and Sunday... so we fed four people for $19.99 plus a tip this evening.
The waitress was quick with refills before we asked. Oddly the place was out of silverware so we ate our cottage cheese with soup spoons and we had regular napkins instead of the ones usually rolled around the silverware. No biggie.
Like I said, we're not expecting five star dining at Steak n' Shake.
