For those familiar with Lima [1]’s culinary delights, it should come as no surprise that it hosts a cooking school licensed by Cordon Bleu (Nuñez de Balboa 530, Miraflores, tel. 01/242-8222, www.cordonbleuperu.edu.pe [2], prices vary by course). The various classes include short-term seminars on Peruvian food, international food, and even desserts.
Another option is the hotel and restaurant management school Cenfotur (Pedro Martinto 320, tel. 01/241-4726, www.cenfotur.edu.pe [3], US$200 per course), whose workshop classes also feature cocktail making and wine-tasting. At either of these institutions you will have to make special arrangements for English speaking classes.
