Costadas. Our host in Nosara recommended that we try the local dish here. We were glad to follow her direction! We were disappointed that they were out of fish when we arrived, but enjoyed vegetable versions instead. Also had a steak version which the teenager loved.
Drinks-- pineapple water and watermelon water were big hits. Banana milk was probably the favorite!
This was our cheapest meal in Nosara, but we had a lot of food and were plenty full.
Note that Rosi is only open for breakfast and lunch. Closes at 3PM, but when we were there at 2, they were already closing tables as people finished their meals.
