My wife surprised me with tickets to Puerto Rico for my fortieth birthday in a couple weeks. We don't have much cash for it (she got an insanely good deal on the tix) but our needs are simple. We'll be staying at a hostel in San Juan with an kitchen we can use, so I figure we can eat out for lunch & have something light at the hostel for dinner. I really know very little about PR besides what I've seen on "No Reservations" & from talking to a few friends of Puerto Rican descent. We don't plan on renting a car but are not averse to walking & are good with public transit in strange places. We'll arrive on Monday, May 06 & depart on Friday, May 10. What do you fine folks recommend for good local food that isn't touristy crap & wont break the bank?
