So next Thursday I will have a 7 hr. layover at SJU on my way to Virgin Gorda. So, I am looking to find a great lunch place that will help me refresh after my red eye flight. I was thinking of going into Old San Juan, and saw some of the recs earlier on the board, but really, for one day what is the best place to hit for a really tasty authentic lunch - it can be in another area, but I would prefer somewhere that has some stuff to walk around and look at. I am only looking to take one cab ride each way. Thanks!
