I had been looking forward to eating this. The Rio San Juan river is home to an interesting shellfish, the freshwater river shrimp. They are as big as small lobsters! Luckily I was able to find a restaurant in El Castillo that had some. Super tasty, and much easier to eat than lobster. Peel the shell of the tail and you get two giant pieces of meat!
Total Cost: $200 Cordobas ($10 US)
