Have previously been to Mariners and it was an amazing experience. They catered well for gluten free (Coeliac Disease). Now, much to my great sadness, I also have a dairy allergy (actually quite common in those with Coeliac Disease), and they struggled to cater for both gluten and dairy-free sadly. The set menu there was one option for starter, one for the main and none of the desserts - it had to be sourced from their Bistro across the road. Food is delicious, and amazingly presented and staff are courteous and helpful. Just not great at catering for all dietary requirements. Please do better - this isn't a choice and I'm still a foodie and like to enjoy good food!
