If you are looking for some regional, local specialities then definitely go for their 'Mutton Handi' and 'Prawns Masala' which offers an authentic taste of ground masalas
Their 'Clay Pot' combination in the Asian section is also good which comes with your choice of gravy and rice
If you want to try something different then go for 'Vegetables in Sambal Sauce', the dish is on a spicier side but definitely worth trying
