Watch where you put the speakers

Finding the right music for your restaurant is really important and "very reasonable", said the experts who provide the service. But this must go hand-in-hand with the right investment.

"The most expensive part is often fitting out the premises," said Ruiz Pardo. He was referring to installing the right sound system. "It must be good quality and have the right number of speakers," said Martínez. These must also be put in strategic places. "Be careful about putting them above tables, for example."
