I know I'm late to this party, but I wanted to add my own rave about the cumin beef at Rice Garden in Washington Square, Brookline.
One thing no one has mentioned, I think, is that the spicy cumin dusted beef dish uses a ton of cilantro as a veggie (ie: stir fried with the rest of the ingredients) Had I known this, I would have gotten over there sooner. It is an absolutely perfect combination of tastes and textures. Wowie.
Ran into Zatan there when I picked up my order. He swore he was going to try something new -- but I am not convinced. After trying that cumin dish I'm not sure I could order something else ...
Another great chowhound find. Thanks.
