I have been to Anant Ashram a few times. Their food is always excellent. Prawns, Clams, Chicken, Mutton, Crab is good, but the best dish on the menu is surely the Shark Masala. It always manages to be bang on the money. The fried fish is tasty as well but you usually will get only one type of fish be it - Seer Fish or King Fish or Pomfret. Their fish curry is nice too. I am sorry to say vegetarians will have only - Bhaji, Ussal and Dal as options.
Their service is legendary. The Khadpe's are very poor at entertaining their customers. They are consistently rude to say the very least. Ambience is basic but usually clean.
On the whole, this place would deserve 5 stars, but their awful service earns it a four.
