my grandson works at a restaraunt "La Tanampa" we cannot translate tanampa. It may be that is a proper name
I think you (or the owners) are misspelling it. It should be tenampa.
The origins of the name "Tenampa" come from the Aztecs who spoke a language called Náhuatl. It belongs to a large group of Indian languages which also include the languages spoken by the Comanche, Pima, Shoshone and other tribes of western North America. The significance of the word Tenampa is "In the murals" or "a place of murals."
