Just returned from 2 weeks in lassi. ate here 8 times tried others but for us this was the best.
the overall feel of the place was more intimate than many. the head waiter spoke pretty good english and was helpful and informative.
While smaller menu than some places food was fresh and excellently presented young chefs from Athens produced specials each evening and the 2 that I sampled were very special.
On several occasions parties of locals were in for special night out, which I did not see in any other resturants, I took that to be an endorsment.
