Yes indeed I had the Malvani prawn curry, just checked the menu again online. The menu states that it has tamarind which indeed adds to the dish being more tart than sugary.
The dish was beautiful, mostly because the prawns were some of the best I’ve recently had in Europe. Big, juicy and tasty. Like they have in Thailand.
As a starter I had a goat kebab - I was really looking forward to having some meat on a stick but they came out with a sort of deconstructed modern kebab! 
No stick, just some meat and sauce on a plate. Disappointing…
This was the curry.
