We ate here on recommendation of a number of people on our tour. It looked a little more expensive than we had hoped to spend, but I must say by the end of it the price wasn't too bad - especially considering what you get!
The food comes in good sized portions (we both had the stuffed chicken breast which was out of this world, and certainly one of my best meals in Nicaragua).
The staff were friendly, spoke fairly good english, service was quick (even though there was a group of around 30 americans who came in at around the same time as us) and the food was delicious - I also liked that you could see the chef as he cooked over the grill.
Highly recommended for parties, a romantic meal for 2 or dinner for the family... I believe even dogs are welcome as a lady on the table next to us had a chiouhoua at her feet.
