In my opinion Passage is the best Indian Kitchen in the area. Chef/ Owner Seth is extremely talented and I applaud him for presenting the selection that he does on his menu. I can assure you that a similar selection would be difficult to find, on a single, menu even in some of the best establishments in India.
Do I like everything on the menu ? No, but that's my personal taste, not because it has not been 'authentically' prepared.
Spicy is not neccessarily hot, it's well seasoned but not overwhelming in heat. Indian cuisine generally has no standard recipes, there are regional nuances, blending more into each other as the world gets smaller, almost everyone has their own personal spice blend or take on every facet of cooking and there are a billion of them over there! No wonder it is confusing.
It appears Don is cooking up something at The Passage, if so please sign me up.
