We have been to Bongos a couple of times on our trips to Orlando. It is actually one of the places we make a point of visiting. The music and environment is very appealing to us and the service has been excellent, especially with regard to my kids. The servers have always been patient and attentive with prompt, pleasant service.
We have a couple of favorites that we order every time we go so I can not speak to the entire menu, but I really like the Cuban sandwich and my boys love the croquettas and tostones.
Previous posters have not enjoyed Bongos food indicating that it is a bit bland, but it is my understanding that Cuban food is not hot or intended to be spicy. It is not similiar to other types of food that one might thing would be similiar such as Mexican. The main dishes that come from Cuba are typically fairly simple meals with chicken, rice, and of course bananas.
If there are other Cuban restaurants in the Orlando area that are thought to be more authentic, I would be interested so we might visit it on our next trip.
