Even the salsas range from subtle burgundy and fiery red, to a rich and verdant green.
But the Mission taquerias are infinitely better than any museum, because they cater to all the human senses.
The flavors and aromas of Mexican food penetrate one's tongue and nostrils. The textured crunch of freshly-fried flautas and taquitos between your teeth and the sound of the serving spoons scraping against the bottoms of metal trays filled with meats and gravies all contribute to the sensory experience.
For me, living on the border of Mexico and United States for over 10 years has given me an immense appreciation for Mexican culture and Mexican food. Never having visited Mexico, I can't say whether the love I developed is for "authentic" Mexican cuisine, or the watered-down Tex-Mex food from chain restaurants. Regardless of where I derive my taste for Mexican food, I know that the Mission District in San Francisco is a fantastic place for me to satisfy both all my senses.
