I am trying to decide between Rasa W1 on Dering and Rasa Samudra on Charlotte Street for dinner tonight. Dining with two friends, one of whom is completely vegetarian, and the other of whom eats fish. Have seen some good reviews elsewhere for Rasa W1, but am curious about Samudra, which is newer and appears to specialize in fish (with some good vegetarian options as well). I'm also interested in any other suggestions people might have for relatively-inexpensive places that are easily reachable from Green Park (on foot, bus or tube). Thanks!
