Pure & Natural is a beautiful restaurant and has a good amount of vegan selections but I wasn't especially impressed with the food itself.
I ordered the eggplant lasagna dish without the cheese and it was pretty good but not great. I think a lot of the flavor in the dish would have come from the cheese (boo). I was glad that it came with brown rice instead of the white rice I'd seen in most other restaurants, and the salad came with a great dressing. I tried my friend's falalfel, and it had a good flavor but it wasn't the authentic falafel that I'm used to in NYC. It was nice and moist, but tasted like it was pan fried instead of deep fried, and although we asked for it on a pita, it came on whole wheat bread, which made it even more awkward. It also had very little tahini dressing, which would have improved the sandwich.
The location is in expensive Condado, which is a very expensive area, but Pure and Natural isn't overly expensive itself. However, it offers no authentic Puerto Rican food and the entire menu appears in English (which is a turn-off for folks like me who want authentic PR food).
