Upscale seafood with polished service and top-tier raw/cooked preparations; expensive but generally delivers, though portions run small and a few service/billing complaints warrant vigilance.
⚠️ Review concerns: This assessment reflects moderate uncertainty due to questionable review patterns. See details in Authenticity Assessment. Ostra delivers exceptional seafood quality and polished service execution that position it among Back Bay's better fine-dining options.
One caveat: Portion sizes on crudo and first courses can feel small for sharing at the price point
