Osianna is located where Voila used to be, next door to the Fairfield Police Department on Reef Road. Mediterranean. They don't have a website and are unable to fax their large-sized menus.
I must tell you though Osianna was fabulous for lunch on Saturday! The unpretentious and very friendly nature of their staff aids in the wonderful experience of dining here. Loved it as expected. We had a great table outside and there was tons of traffic to watch because of the fair nearby on the green--we almost witnessed about six car accidents and several road-rage incidents while sitting in their outdoor corner patio! I had mussels with caper berries (my favorite--I LOVE LOVE LOVE the large caper berries and you don't get them a lot!) and their lunchtime fish entree (Branzino--a type of bass filet I believe)--very good. My mom had their onion soup special and my sister I think got their calamari. My sister was wishing she ordered the eggplant chip and tatziki app because that looked incredible, as did their fresh tuna nicois salad. My sister had their beet and goat cheese salad. My mom had their croque monsieur sandwich that looked incredible. We did not have dessert, although they all were interestingly different than the norm. They also said they while they DO accept lunchtime reservations, they do not at dinnertime but if you go at dinner and there is a wait, they will take your cellphone number and call you when the table is ready. Their dinner menu looks even better. A friend of mine dined there on a Tuesday night and had diver scallops with asparagas and white beans she said was "Outrageous." And she also said their martinis were excellent - had a concoction with citron, chambord, and apple pucker. Enjoy!
