I would recommend the restaurant Octavia for special occasions. The decor inside is neutral- I think it's like so the can food portray the majority of the color. The food is portioned ever so appropriately. It was also picked as one of the top 100 restaurants by Michael Bauer. And lastly, it is the sister restaurant to Frances- which is another one of my favorites here in the city. If all of that wasn't convincing enough, here are some pictures of my experience there.
I did not try the squid ink noodles but heard they are fab. I can't wait to come back here for another special occasion.
