Amazing hair and beard cuts, but as a caveat, look up instructions of what you want your hair to look like in Spanish before you go, or this becomes more of a gamble. Even if they don't do exactly what you wish though, it still beats Supercuts.
Also, make sure you have some money in the bank before you go, just because this does tend to be a little pricey (and reasonably so). A great place to go to pamper yourself.
