An excellent and unique culinary experience near the San Miguel Mission, Kakawa offers rich, Meso-American chocolate drinks--highly recommended. Their website describes their drinks much better than I could:
Re-created several elixirs based upon the chocolate that was consumed in pre-Colombian America. These exceptional drinks were reserved for the powerful elite and for special ceremonies (Cortez, for example, drank chocolate with Montezuma when he first arrived in Tenochtitlan). These elixirs are full of intense flavor, highly spiced with a wide variety of native herbs, flowers, and chilis.
