Tandoori is the best bet as it is baked and not cooked in oil, have plain rice, a salad, syn-ing some poppadoms is a great idea too. Your alternative is to use flexible syns and say i'm going to have a chicken balti, a naan bread and raitha, visit the SW site (or here) and get the syns and then stick to that amount. I have done this twice for various events and it's worked well for me, i have still ost on both occasions despite having everything i wanted including a really nice ice cream follwing a thai meal!
