It's hard to tell which you should skip without knowing what your looking for.
Personally I would drop both Greens and Dosa.
Most people go to Greens for the view, not so much the food. I don't think of Dosa as a destination place either, it's very popular among the yuppie crowd but I could think of much better in this city for both Vegetarian and Indian if your priority is the food.
