Since the second we got home I have been trying to recreate the "made-fresh-at-your-table" guacamole experience we had at Pipi's with no luck. The food was fantastic and plentiful (I think most of us shared entrees), the drinks were never empty, and that GUAC! Oh man, I wish I was there right now.
One thing you'll never find lacking in PVR is great food. Check out some of our favorites:
Oscars (by the bridge) is a nice open air place on the river. Very romantic (ok, if you're not there with four other people that is).
Pipi's
There is a little place just as you enter the Marina that advertises $1 Coronas. The food was fantastic and practically free. And those dollar beers come with a free shot of tequila.
We went to the Fiesta at the Mayan Palace, which was incredible. Pricey, but worth it just for the food alone.
