Let's start with I'm a huge fan of Lebanese Taverna, but not the Tyson's Corner location. Overall, the food and service are both measurably worse at this location than their other locations. We chose to go to the Tyson's location for a large family gathering because it was more convenient geographically and it was a mistake. We were in a back room, which seemed great because it was more private, but everything took forever. 3 hours into our meal, we'd eaten appetizers and entrees and had to flag a server down to get dessert menus (we ultimately passed on dessert because of the time). The dish I ordered, which is a favorite from their other locations, was cold and the sauce was clearly not fresh. I'm not generally a complainer, but it's stunning how different the quality is at Tysons vs. the Arlington locations.
