Marked menu, shared, Allergen-marked menu and aware staff but shared fryer / prep. Cross-contamination risk acknowledged.
HappyCow describes an extensive, clearly marked vegetarian section with 'quite a few vegan options' and a separate vegan menu. However multiple reviews warn that the vegan menu is not fully vegan (items may contain dairy or egg) and that staff knowledge varies. Diners must explicitly request vegan versions and verify ingredients. Shared kitchen, no dedicated equipment.
Honest caveat: Vegan menu may contain dairy or egg; diners must verify each dish with staff.
