If a guest asks you a very nice place to eat, what do you suggest?

Hard Rock Café, because when you are there, it looks like you having dinner or snacks inside a musical museum!! Inside you can find several pieces that once belonged to famous musicians, some have died, some retired, etc. There you can eat American style foods, hamburgers, hot dogs. And a funny thing is that in the menu they give names of guitars to the burgers and hot dogs. Once I recommended this place to a guest and when he came back he gave me 2€!!! He just loved it!!!
