The Terrace Restaurant

From Muppet Wiki

The Terrace Restaurant, so identified in The Muppet Movie companion storybook, is where Kermit the Frog and Miss Piggy have their abbreviated romantic evening. The staff includes a sarcastic waiter in short pants and piano player Rowlf the Dog.

The restaurant is attached to the Quiet Little Motel, and for 95 cents, offers sparkling muscatel, one of the finest wines of Idaho.
