Catalan food and phenomenal service are the stars of Niu Kitchen. The tiny restaurant almost seems out of place, stuck between a mini-mart and an optometry office, until you step inside. That’s where co-owner Karina Iglesias greets guests with a smile, a table (assuming one’s available; best to call ahead) and a choice wine selection, while chef Deme Lomas crafts tapas, poached eggs, wahoo tartar, oysters and other dishes in a small but efficient Niu Kitchen. 134 NE 2nd Ave., Miami, FL 33132
