Nature Sushi Bar is highly praised by about 95% of reviewers for its fresh, well-made sushi, creative dishes, beautiful presentation, and cozy, plant-filled atmosphere, with many calling it the best sushi in Florianópolis and emphasizing the excellent value, especially with the Festival menu. Service is described as professional, warm, and attentive by the overwhelming majority, with frequent mentions of staff like Ana, Lucas, and Bernardo going above and beyond; a handful of reviews attribute their positive experience specifically to staff members, while one negative review reports a notably bad experience with slow and inattentive service from a particular server, especially when dining with a child.

Critical feedback is rare, with about 5% of reviews mentioning issues such as unclear repetition policy for festival dishes, sweet sushi, underwhelming main menu items for some, and concerns about space for larger groups or comfort with floor seating.
