The food was delicious, and there was a wide variety of things that you might initially think a celiac wouldn't be able to eat.
The staff was also very pleasant and friendly, and they gave us recommendations on both the dishes and the quantities to order.
We did find the atmosphere quite noisy; we would have been better off in another room further back, which was almost empty.
Even so, if we return to Madrid another time, this is a place we would definitely return to!
