I'm going to Nicaragua!
I found a couple of awesome threads on food:

I'm wondering if anyone else has anything to add on restaurants, markets, or anything else. I think I'll be in Rivas for a few days and San Juan del Sur for a few days, probably Mangua for at least a day, and otherwise open to go wherever there's good chow and fun to be had.
