Unfortunatley, this was not as good as expected or hoped. We came here due to the Happy Cow app reviews.
However, the Gluten Free bread has egg in it, so they can't do vegan and gluten free bread of any kind. (They do acknowledge this on their vegan menu.) They agreed to add avocado to replace the bread. Then they came back to tell us they also didn't have any GF Vg hashbrowns, so they agreed to add extra chips to replace the hashbrowns.
Then we waited...and waited. When it finally came, the meal was small. They forgot the mushrooms (standard with the meal), and they forgot the avocado, which was to replace the bread, and they didn't give us the extra chips that were to replace the hashbrowns. They did get us the avocado when we asked, and they put a rush on the mushrooms, but I'd nearly finished eating when they came.
Overall, this meal was expensive, as it was small and lacklustre, and we left hungry.
The place was initially busy, and people generally seemed very happy with their meals. So I think they just dropped the ball on the intolerance menu.
