Zona Rio, Tijuana
The Zona Rio is the Tijuana's most modern commercial area with malls, restaurants, museums, nightclubs and hotels.
The Centro Cultural Tijuana is one of the principal attractions in this area. It has a planetarium theate, and also contains a museum, the Museo de las Californias.
I used to go to this area a lot for dinning specially to Plaza del Zapato (the name cames because of its shoe stores). Another nice area to have fun at night is Pueblo Amigo.
