I had the opportunity to get a bite to eat at Fiesta.  I was pleasantly surpised at the quality of the wings.  Lightly battered served with carrots, hot sauce and real blue cheese dressing.  The wings were meaty.  I had the chicken/beef/schrimp fajita which was also good.  It was a Sun night, live music.  I think the wings and fajita was about 7500 colones.  The place has a nice active atmosphere and, yes, there are a few chicas that seem to be gringo friendly  

 , just it is not as blantant as the regular places.  I was actually searching posts and read there is ladies night on Mondays.
