The first time I went to DC Coast, I went with my boss. It was a very fancy lunch. The actual dining area of the restaurant is quite large, and you find yourself rubbing elbows with alot of DC's hot shots, but don't let that frighten you. When I went, I ordered the DC Coast Salad, which was basically mixed greens topped with finely chopped boiled egg, bacon, tomatoes, and blue cheese. I then ordered the crabcake appetizer as a lunch meal, which came with two chunky crabcakes and a large side of thick french fries. My coworker had the salmon topped with caramalized onion, and both were extremely delicious. I've heard, however, that the seafood isn't exceptional, so I'd stick to the crabcakes, which happens to be their specialty. My boss's favorite is the gumbo, as he evidently gets that every time.
For dessert I had the Warm, New Orleans Style Beignets, which came with Café Au Lait Crème Brulée. The Crème Brulée was just right, and the dessert was certainly large enough to share, as it came with four of the beignets topped with powdered sugar.
It's certainly not a place you'd want to try often because your wallet would run dry, but it's definitely a place you'd want to check out once for a special occassion.
