Name Of The Restaurant

Two senior couples are walking along, wives in front, husbands in back. Herb says to Sam:

- Gee, we went to a new restaurant last night and had the best meal ever. Good prices too.

Sam says:

- Well, we like to eat out too. What was the name of the restaurant?

Herb says:

- You'll going to have to help me out here a little. What's the name of that pretty flower, smells sweet, grows on a thorny bush?

Sam says:

- How about rose?

- Yes, yes, that's it! - cries Herb, then calls ahead to his wife.

- Rose. Hey, Rose. What was the name of the restaurant we ate at last night?
