The Restaurant

An elderly couple had dinner at another couple's house, and after eating, the wives left the table and went to the kitchen.  The 2 gentlemen were talking, and one said, "Last night we went out to a new restaurant and it was really great.  I would recommend it very highly."  The other man said, "What' is the name of the restaurant?"  The first man thought and thought and  finally said, "What's the name of that flower you give to someone you love?   You know, the one that's red and has thorns?"  "You mean a rose?"  "Yes!  That's the one," replied the man.  He then turned towards the kitchen and yelled, "Rose, what's the name of that restaurant we went to last night?"
