I've been frequenting BRG (as its known to the locals) for several years at both their Leesburg and Ashburn locations. I've never had a bad meal at either location and the service is top-notch. I love the fact the Ashburn location is next to my favorite movie theater so I can get a pre or post film meal.
Their soup of the day is excellent; the daily lobster bisque is divine and if you're there on a day the chicken tortilla is served, be sure to order at least a cup if not an entire bowl as it too is delicious (I have friends who specifically request we hit up BRG on chicken tortilla soup night).
The Ahi tuna salad is very good and another favorite.
As I can no longer eat gluten, I can only attest to the awesome steak and cheese egg rolls from several years' prior experience. The spinach and artichoke dip is still a table favorite.
I now order both the ciabatta chicken sandwich and prime rib sandwich without bun, both are great.
Prime rib and barbecue ribs are also table favorites.
Came here twice for Sunday brunch and it was amazing. They bring out hot fresh churros liberally dosed with powdered sugar. The aroma alone is tantalizing. Sadly, I cannot eat them but my friends have no problem inhaling them. They'll bring you more too...
Save room for dessert!
Service here too is excellent. I find prices reasonable and well worth their value.
Word to the wise: this place gets packed so be sure to do a call-ahead to reserve a table.
