In Mexico City, the center of mariachi music remains Garibaldi Plaza. Mariachi musicians fill the plaza to solicit gigs, from individual songs for passers-by to being hired for events such as weddings and baptisms. They even stand on Eje Central in front of the plaza to flag down passing cars. In 2010, the government renovated the plaza to make it more tourist-friendly, adding new paving, gardens, police, security cameras, painted facades, and a museum dedicated to mariachi and tequila. Although mariachis can be hired in Mexico City over the phone or on the internet, many people still prefer to come to the plaza, hear the musicians and haggle over the price. About 2,500 mariachis hold union cards to work in the plaza, but as many as 4,000 may circulate through on a busy weekend.
