I was taken out to Anthos last night with some friends. I didn't have particularly high expectations, but I was pleased with the experience overall.
There is a coat check right by the front door (which saves you having to track down someone to get your coat as well as a moderately sized bar. I was seated with my party straightaway. For some reason I expected the place to be on the empty side but at 6:30 pm (Saturday) it was about 3/4 full.
Service was attentive, if overmannered - they were clearly reading off a script. "Have I helped you to make a decision this evening" etc. a few bobbles where the wrong apps were delivered to the table and so on, but corrected very quickly. they did not rush us even though we were there for 3 hours.
drank a Greek white wine throughout the evening, which was fine (I didn't catch the name but it's 14 a glass).
The room isn't as dismal as I'd read - simple but comfortable - but what's with the ONE bathroom for women? right next to the kitchen?
anyway, on to the food.
the free starter was a tasty little sampling of whipped fish, lamb dumplings, etc. the winner were little fried cubes of manouri cheese. we also received an amuse bouche of raw fluke that was eh.
appetizers were a snail/cheese combo (tasty) an absolutely delicious quail that came with a little cheese casserole on the side (the best), meltingly delicious sheep milk dumplings with mussels and trout roe, and a pork belly/pasta plate (a special) that came with very crispy, porky bacon on top. All the apps (except the snails) were very generously sized (and priced - they run 16-20 dollars!)
Mains were good as well - I had a decent turbot with excelletn fried oysters. The lamb received accolades, and I sampled a pleasant loup de mer (the diet option, apparently - grilled with a sad-looking ramekin of steamed veggies that could have come from a cafeteria)
Desserts were delicious - the baklava, a goat cheesecake and the grapefruit-ginger sorbet were the winners.
All in all, I enjoyed my meal at Anthos. While I did not pay, I peeked at the check and it was $440. I don't know that it is good value, but if you are in the area you could certainly do worse.
