I've been to Excellensea three or four times, and tried various seafood dishes, including bangda fry, bangda gassi, squid gassi, meen pulimunchi, prawns koliwada, chicken liver masala fry, etc. While all were uniformly excellent, the best value of all is the bangda gassi (Rs. 70), with a plate or two of neer dosas (Rs. 45 for a plate of four). Highly recommended.
