Agree about chicken/lamb shashlik, lovely and tender and you get nice chunky veg with it which is much nicer than a tiny plastic bag full of warm salad (gak!). I sometimes have the saag paneer too, I used to worry that they put lentils in it but I'm pretty sure now that's not the case - it's just finely chopped onion. You can always ask I suppose! I would stay away from korma or creamy sauces as they are likely to be thickened with flour.
With chinese I go for the chicken foo yung and dry ribs - I usually have to ask for these specially, just ask them to hold the sauce and make sure they don't come with a batter coating or you will be in for hungry heartbreak when you get it home (I'm still bitter about that batter).
From the chippy you can get the roast chicken quarter or some places do halfs, and nothing much else so make sure you've got some salad in at home.
If I'm going to have indian/chinese, I always make sure I cut a few carbs out of the rest of my day just to compensate for any 'hidden' ones that might be in there (e.g. milk mixed in with the foo yung).
