Considering the Crowne Plaza Monterrey in Monterrey?

Aguas frescas = fresh waters by arteimagen
When travel trought Mexico you can taste a variety of natural fresh water, most common are, lemonade, jamaica (red colored water made from saborizated flowers), orchata (white colored water made from rice and cinnamon) and tamarindo (brown colored).
These fresh water are sold everywhere even in streets but try it only in restaurants or hotels by safety.
