I go to Tanino quite often on Saturday evenings, also due to the presence of gluten-free dishes for my celiac girlfriend.
The place is very warm, welcoming and not very noisy.
The service is really good, especially due to the presence of a very friendly waiter who knows how to handle customers well.
The food is normal, respecting the quality/price ratio. (Slightly lower than average)
The Neapolitan dough is very distant from the original one but all in all it is quite pleasant.
Some desserts are better than others (the cheesecake is average, the hot cake is evidently frozen and heated in the microwave, the mascarpone is delicious and the homemade tiramisu is highly recommended).
Objectively, for the province of Mantua, it is an interesting place to spend a quiet and unpretentious Saturday evening.
