I'm going to be in San Juan (first time) for just a few days, traveling solo. Staying in the Condado Beach area. When I travel, I like to sample authentic local cuisine, and love street food. I don't mind if it's touristy or popular, just that I'm not getting a tourist version of the food. I also try to avoid tourist prices, but sometimes it can't be helped.

I've done a little research, but I'm guessing much of what I'm looking for is going to be hard to find on the internet.

I plan to spend most of my time on the beach or in Old San Juan. Are there food trucks or food stalls in those areas? Any recommendations on great casual restaurants nearby where I can get authentic versions of mofongo or any of the various rice with seafood/pork/etc. dishes? Hole-in-the-wall recommendations welcome!
