Dairy-free

Verifiably Safe, Either a 100% dedicated kitchen (no allergen on premises) or actively certified by a recognised accreditation body for this allergen.

As of June 2024, the venue is reported fully vegan, meaning no dairy is present on premises. Confidence is moderate rather than high because the venue's own website (pre-2024 content) listed cow's milk as one of five cappuccino milk options — though all 2024–2026 reviewer accounts consistently describe a 100% plant-based offering, suggesting the transition has occurred and the website is outdated.

Coeliac · Gluten-free

confidence 0.55 ·

Marked menu, shared, Allergen-marked menu and aware staff but shared fryer / prep. Cross-contamination risk acknowledged.

The Atly GF community platform classifies 100% BIO as 'Accommodating gluten-free' with acknowledged cross-contamination risk and trained staff. The buffet offers multiple gluten-free options and an allergen list is available on request. A HappyCow reviewer (Sep 2025) noted a vegan gluten-free tiramisu and found staff 'with solid grasp of various allergens,' while also flagging 'no clear menu for à la carte.' A separate Atly reviewer reported 'very limited gluten-free options' at breakfast specifically. No dedicated GF kitchen, no coeliac accreditation, and the shared buffet environment means contamination risk persists.
