THIS RESTAURANT IS CLOSED The Lebanese Taverna group has reached out to areas far beyond its original dominion: Arlington County and downtown DC. Today, the group has edged into Rockville proper with a sit-down/take-out in the Town Square area. This casual place serves the same Lebanese foods but without white-tablecloth fanfare. Craving hummus, stuffed pitas, falafel, and those hot beefy appetizers known as kibbeh? You can stock up here, then stroll outside to relax in the plaza and watch the world go by.
