Location from Gravity Falls by Alex Hirsch / Disney Channel
Gravity Falls' main diner: built inside a converted redwood log, staffed by Lazy Susan, and the place where most of the town's adults eat, gossip, and occasionally witness something they'll have erased.
Greasy's Diner is the community center that Gravity Falls pretends it doesn't have. Every important local — Stan Pines, Sheriff Blubs, Manly Dan, Old Man McGucket, Robbie Valentino — turns up here eventually. Lazy Susan is the axis around which the diner rotates: cheerful, slightly disorganized, genuinely kind, and unaware of approximately half of what's happening around her. The pancakes are the best thing on the menu. The manliness machine near the door once shattered when Manly Dan used his pinkie finger. The diner survived Weirdmageddon intact.
The outside is shaped like a fallen redwood log, with a stump on the right side as if the tree was felled right there. Sign reads 'Greasy's Diner — We Have Food.' A small banner nearby says 'Eat.' Inside: a typical American diner with a counter, booths, and a 'Test Your Manliness' grip machine near the entrance.
