My co-worker asked me for recommendations on an inexpensive but good sushi place between work (downtown DC) and her apartment (Woodley Park). She generally goes to Umi in Woodley Park but says she ends up spending more than she'd like there ($25) and is looking for other options. I am not familiar with the options on that side of town and could only think of Kotobuki in the Palisades or Momiji in Chinatown. Is there any other place I can recommend to my co-worker? I want to keep my reputation as the office guru of DC restaurants. Thank you!
