Small restaurant in the main Bethesda restaurant/shopping area. If you can get past the crazy parking situation, Luke's is worth it. Not cheap, but well worth $17 for a top flight lobster roll. Service is fast and eating outside on the benches is a good way to dine. There's about 25 restaurants within a 1,000 yard radius -- if you want fancy, go somewhere else. For an authentic lobster roll, this is the place.
