Being both vegetarian and gluten free it's not easy finding a decent burger but I would recommend The Rockstone, especially if you are vegetarian or have dietary restrictions. There were plenty of burger options and staff were very helpful with making this gluten free. I got the veggie patty - which wasn't fake meat, it was actually made of vegetables and really delicious. Service was a bit slow, however I think this was just because we were a large group. So trying to cook 11 different burgers at once can't be easy! Staff were friendly and all of our orders were completely right. I Would recommend and would go again.
