OTO receives about 70% highly positive reviews for its unique Japanese-Italian fusion cuisine, with standout dishes like milk bread with tofu dip, lobster pasta, crudo, and inventive desserts such as the Amalfi lemon and tiramisu, often described as "exceptional," "delicious," and "must-try." Roughly 15% of diners feel portions are extremely small for the price, using phrases like "tiny tiny portions" and "expensive for what you get," and some note that fusion elements don't always work (e.g., lemon in cacio e pepe, scallops overwhelmed by cheese). Service is generally friendly and professional, but about 20% report inattentiveness, lack of wine knowledge, or long waits, particularly during busy nights, and there are occasional issues with denied late service or missing dishes. The atmosphere is widely praised as cozy, stylish, and upscale, with reviewers highlighting the beautiful setting and modern, comfortable ambiance, making it popular for both special occasions and casual dining. A minority (about 10%) express disappointment, citing overly salty food, unclear menu descriptions, or poor value, though even critical reviews sometimes acknowledge the high culinary potential and some memorable dishes.
