What is Dennis’ opinion about the restaurant?

M：I can’t hear a thing over this music, and we can’t even talk. Let’s go somewhere else for dinner.
W：But Dennis, the food will be here any minute.
M：So what? We’ll just tell the waiter to cancel our order.
W：I’d rather stay and eat here, if you don’t mind. Why don’t we just ask them to turn down the music? Let me get the waiter’s attention...Waiter!
