We visited the restaurant at the weekend, and were surprised by the lack of custom, most of the tables were empty. We only visited this restaurant, as the Talisman was full (Why is this not on the list?)
The location is poor, it requires a complete refurbishment (appears nothing has changed in 38 years), service is good, if a little over attentive. The food was ok, nothing to shout about.
I would recommend this restaurant for a special occasion (formal setting) or an intimate meeting, although the waiters will be asking you how's food or changing plates every minute.
A particular disappointing aspect was the waiter pushing for a tip on presenting the bill. I was going to give a good tip, until he became pushy.
Seven Seas is by far a better restaurant for fish. The Octopus and seafood platter are clearly better than the Tamarind offering.
