A new Spur Steak Ranches found under Build Mode / Community Objects, costs 0. It's a rabbit hole. You need Late Night or a later pack for the diner to show in your game. I've used a 40x40 lot.
For the best T-bone steaks and spare ribs in town.

PS. I've used the Panarottis full set including lot (MediaFire) and replaced only the Diner.
