Have you tried out the newish restaurant at Reston Town Center - Pisco? I have to say the food is delicious and their Pisco Flight is a lot of fun! The ambiance is casual, don't expect a lot of mood lighting as its a little bright in there - even in the later evening timeframes. My favorite menu item is their Ceviche, although their empanadas are pretty delicious too! Let me know what you think!
