street vendors

You can easily tell which street vendors are safe to eat from, just look for the ones that are really busy.

As for the guys walking the beach, nothing wrong with them either. My young daughter and I have eaten from them many times and have had no problems. What I look for is if they have a handful of skewers then most like they have just come off the grill. If they have just one or two left then I might be a little cautious.

Yelapa and Majahuitas are both gorgeous, you will love them. And make sure when you get to the waterfall on Yelapa you jump in, take a moment and take in your surroundings and marvel at the beauty of it all.
