No go on Bongo's:
We had dinner there a few years ago.
Service was not good, music too loud for conversation, and food was plain, as in bland. Not spiced (different than spicey everyone), and just bland. The staff seemed to us to be too busy standing around talking to each other and trying to look hip, rather than doing their jobs.
Having since had authentic Cuban food elsewhere, Bongo's really was not very good food, period.
If you want real Cuban food, there are much better choices fairly close by.
That being said, the walk-up window on the front of the building is okay for a snack. I tried that last year in a moment of desperation, and was pleasantly surprised at both the quality and price.
