I first visited Maggiano's in the mall in Tyson's Corner a decade ago during a business trip. I had such fond memories of my prior visit, that I made a point of eating there again while visiting DC over the Memorial Day weekend. The atmosphere and service is great, the value is good for the Tyson's Corner/DC area, and the food is incredible.
My Mother is 100% Italian, and I always imagine that I am visiting my relatives in Italy when I dine there! I had the eggplant parmesan and it was out of this world! I can honestly say that it was twice as good as any other eggplant parmesan I have ever had, and I have made and eaten A LOT of eggplant parmesan in my life. It was so good that I brought the "take home" second entree home in my cooler so that my son could taste it! Two separate meals for $12.95 was a steal! I also love the Italian bread with the extra virgin olive oil provided at every table.
In an effort to provide full disclosure, when I was finished with my meal and the waiter brought my "take home" bag, I noticed a 3/4" cockroach walking across my table. I don't know if it was on the bag or had been lurking around the table the whole time I was eating. I suspect that many restaurants have issues with cockroaches, especially in areas where they are surrounded by other restaurants. Although that was the only thing that prevented me from giving the restaurant 5 stars, I did not let it ruin my wonderful meal and did not suffer any ill effects.
