This is definitely not a small local trattoria.  I would consider the Baglio La Pergola to be a rather upscale restaurant.  It is located in the modern part of Ragusa (I prefer the older section).  Ragusa is essentially divided into two towns - new and old.  I had a wonderful grilled swordfish while my wife had an tortellini dish with seafood that was also very good.  The restaurant has an extensive wine selection.  I would recommend this restaurant if you are looking for a special evening out.
