What reviewers say about the free-from experience

  • vegan and plant-based options
  • gluten-free options
  • coeliac awareness
  • staff allergen knowledge
  • nut allergy handling
  • shellfish allergy
  • intolerance-matching menu tool

Reviewers frequently describe strong vegan and plant-based choice, with several naming a favourite vegan katsu curry and other meat alternatives, alongside gluten-free options and vegan dessert or ice-cream swaps offered when someone couldn't eat the standard cake. Many mention staff talking allergies and intolerances through: servers are described sitting down to go over the menu, checking dishes for a diner with coeliac disease, double-checking a nut order with the kitchen, and swapping prawn crackers for vegan ones. A shellfish allergy and general intolerances also came up, with one reviewer noting a scan-a-code system to enter intolerances and see matching dishes.

Summarised from 31 allergen-related public reviews. feefrae is not a medical authority and does not verify individual reviews — this describes what diners discussed, not whether the venue is safe for your needs. Always check directly with the venue and do your own research.
