If you are looking for bottles of juice, try the Little Sandwich Hut in between Negril Escape and Mirage, across the street. You get to pick out your fruit and Ali will fresh squeeze it, by hand, right in front of you. The "hut" is no longer there (Ali said he lost it, but I didn't ask what happened), but you will see Ali sitting in front of a little fruit stand with a makeshift tarp, under which he squeezes fruit into empty rum bottles. Make sure you have 15 minutes to spare, as this isn't 7-11. However, you will be hard pressed to find juice that is any fresher.
