"As the official opening ceremony, Fiesta Fiesta transforms the Hemisfair into a giant party complete with live entertainment, a fireworks show, and festival fare from vendors like San Antonio Gorditas, Palenque Grill, and Dolce Kupcakes. The event takes place on Thursday, March 31 from 4 p.m. to 10 p.m., and is free to attend." - Polly Anna Rocha
