I brought my friend who has a gluten intolerance to Birdhouse because the menu offered many gluten free options. However it's not explicit that the gluten free pancakes are actually waffles, of which are very small and a bit hard. My friend was really disappointed by this, we've been to many places which provide GF options and the waitress did not make it clear the pancakes ordered would actually be waffles. Not only that but my pancakes were very poor, they tasted heavily of baking powder and it wasn't a great experience overall. I think for spending £30 really it was all style but no substance. Not making it clear with your menu that the GF are an alternative choice is pretty poor. Disappointed as so many people had recommended yourselves but it fell short with both service and taste. The cafe was also very cold. I would say to people seek alternatives, there are so many options in Sheffield. Really disappointed.
