I'd like to get takeout Indian food for Christmas Day dinner, for a group of 15 people (of which 3 are children), and 4 are strict vegetarian. What places in the Cambridge, Belmont, Watertown, Arlington, Somerville area would you recommend? I'm looking for a good combination of decent food, accessible location (where I can easily park my car and pick up, and I can park in residential Cambridge spots), and reliable (order done on time, packed up correctly, not missing items, etc.). We haven't eaten out Indian food for years, so really don't know what's good out there anymore. Thanks\ for any ideas.
