Absolutely fantastic experience at Bill's in Cardiff Bay.
We turned up without a reservation and despite the place being quite busy, we were seated promptly and drinks orders taken quickly.
I'm Coeliac which means boring gluten free dining, but in Bill's there is a whole gf menu so I didn't feel left out. I had the Fish Pie and Banoffee Sundae, both of which were different from usual gf options.
They also did a gf IPA which I wasn't very keen on but nice to have the option.
We were served by Gabriel. He's an absolute treasure.
If you're gf, you should deffo give the place a try!
