In conclusion, I can honestly say that I have not tasted such a welcome variety of delicate flavours in a very long time, and I only wish I could afford to eat at Club Gascon all the time. Whilst the prices mentioned above include VAT, they do not include coffee or service. The team of waiters seem to glide effortlessly around the room and operate like a very well integrated team, so that service is ever present, without you being aware of it, and is flawless. Booking is definitely advisable. Especially good are the Duck and Venison meals.
Service is prompt, staff are welcoming and the window decor is very attractive.
If you don't like piano music avoid those two tables near the Joanna.
