I was there a couple of weeks ago.
There are two areas to the restuarant, upstairs and the downstairs where you enter. Upstairs feels more private and overlooks the way in so you get to see people arriving and its smaller so feels a little more private perhaps
We went on a Saturday and phoned ahead to book. I advise doing the same, we went early at 10.30 but by 11.- 1130 it was very very busy so booking is a good idea perhaps.
Food is excellent European Fusion ish stuff like you would get at Mezzo in London or a Conran they have an alternative expensiv Sushi menu too so you have two restuarants in one dependin on your preference.
I had john dory with an asparagus and new potato salad, was very nice, my frineds raved about the thai prawn sald starters.. and the desserts were fabbo..
Friends had lamb cutlets, grilled salmon and i think one had fillet steak.. all very good though!
Yes its pricey for spain, but iff you paid more in Londonyou would be happy.
We spent 230 Euros but did spend 50E on one bottlle of wine to bump the total up..
You woudnt want to try and be cheap in there it woudnt be right.. crowd is monied europeans..think shirts rather than t sherts and glamour rather than tousled. mostly Spanish.. and I think we ate next to one of the owning family.
Go.. its part of the experience!... and its effectively free next to the entrance price..
The sushi looked very very good indeed....
