Officina del Riso Navigli

Nearly the entire menu is gluten-free by formulation, since the kitchen is rice-based. EU allergen codes (code 1 = Glutine) appear on each dish to identify gluten-free items, and some dishes are explicitly named 'senza glutine', including a Cotoletta senza glutine and a tiramisu made with 'savoiardo senza glutine'. Multiple symptomatic coeliacs at this Navigli branch report no reactions, and staff are described as knowledgeable. However, this branch is not a dedicated gluten-free facility. Normal bread is served at some chain locations, and no dedicated fryer is noted for this branch. A community reviewer on the Isola branch's listing claims AIC (Italian Coeliac Association) accreditation for the chain, but AIC is not on the verified accreditation list, and the claim comes from a single reviewer rather than an official source.

Many dishes are clearly vegetarian from menu descriptions, including tomato-burrata risotto, truffle risotto, La Parmigiana di melanzane, Zucca Balls, Libanese gunkan, I 3 Finocchi, Insalata Invernale, Quinoa Salad, and others. Per-dish allergen codes flag fish (code 4) and shellfish (codes 2, 14), assisting identification. Meat and poultry do not appear as EU allergen codes but are evident from dish descriptions. Gluto lists the venue as 'suitable for celiacs and vegetarians'. HappyCow classifies it 'Veg-options (Lacto, Ovo)'. FMGF notes 'good vegetarian options'. The kitchen is shared with meat and fish preparations throughout.

For each dish, allergen code 7 (Latte/milk) is listed. This makes it possible to identify which items contain dairy and which do not. A number of dishes are naturally dairy-free, including Battuta di manzo, Quinoa Salad, Selezione Italiana di salumi, Polpopop, Libanese gunkan, Favignana gunkan, Presa di wagyu, and others. All risottos can be ordered in a '100% vegetale' version. That version swaps the standard butter-based mantecatura for a preparation using white cabbage, cannellini beans, and oil. Across multiple branches, FMGF reviews note 'good for dairy-free'. The kitchen is shared, and dairy is used extensively in standard risotto, gunkan, and dessert preparations.

The official menu notes that all risottos are 'disponibili in versione 100% vegetale con speciale mantecatura a base di cavolo bianco, fagioli cannellini e olio'. This means any risotto can be made vegan by substituting the standard mantecatura with a plant-based version. Dishes carry allergen codes for dairy (code 7) and eggs (code 3), which helps identify items already free from animal products. Several HappyCow reviewers report that staff are knowledgeable about vegan options. The venue offers 2–3 confirmed vegan risotto choices, including truffle, aubergine, and seasonal variations. Officina del Riso Navigli is otherwise a non-vegan Italian restaurant that serves meat, fish, dairy, and egg dishes, all prepared in a shared kitchen. Customers who want the vegan risotto must request the plant-based variant.
