Demands how hungry you are but for a couple I would go for something like:
2 x starters - chicken tandoori/other
2 x curries - suggest getting two different meats and two different types of spice/sauce e.g: chicken pasanda (creamy but based), Goan salmon (garlic, pepper, coconut base) or lamb shishlak (tomato, pepper, sweet and sour like base). Just any mix of two different and maybe go for house/regional specials for something different)
1 x rice - pilau or coconut
1 x peshwari naan (sweet coconut stuffed) or garlic if not keen on coconut
1 x side - sag paneer (spinach cheese), aloo gobi (cauliflower potato) or brinjil based (aubergine)
Hope that’s helpful?!
