I have been 3x since my allergies have flared up and they have been incredible!
First time they were really busy so I took my own bread, which they happily accommodated! Second time was lunch so I just had a salad. Most recently they spent the time going through the entire menu looking for suitable dishes for me.
Each time I've been they've been welcoming and understanding. They use a different space for gluten free. Their fryer is vegan friendly and coeliac friendly.
