Perla is one of those places that gives a feel of a missing engine... It sort of goes, but never smooth. Sorry for the technicality! :-)
The entrance and design were not attractive at all, but we dropped in simply because we were hungry and wanted to eat something with a pronounced Latin flavor.
Menu was not impressive, or maybe we were expecting more from a Portugal restaurant. Maybe the owners are Portuguese, but their restaurant was not. Just a usual "americanese" food. It was ok, but nothing special to talk about.
Service was on a slower side, which annoyed a bit too much, keeping in mind that we really wanted to eat like right now! Yet the server was polite and nice, so after all we've survived and were ok.
Overall - I would eat that for brunch, or when hungry - but neither the food nor the place are not worth travelling distances to taste.
