It is extremely impressive that Oak presented us such a fine experience on its 5th night of being open. Decor is lovely; very welcoming staff; and service by Matthew was impeccable. The octopus appetizer was the best I have ever had (including Italy!), and the porterhouse and truffle fries were divine. Their other restaurant, O-Ku, is a favorite, as well; Oak is a welcome addition to the Southpark restaurant dining scene. I'm looking forward to returning, AND to their addition soon of a Sunday brunch!
