Fifteen London

I went to the Dining Room downstairs (slightly more formal dining than Trattoria upstairs) and found it to be faultless. The service was attentive but not over-bearing, the food absolutely delicious (I'm a veggie and so to get unusual, but tasty food in this kind of restaurant is a real novelty!) and the price, whilst expensive, not beyond what you would expect in this kind of place. The only reason why I didn't rate it more highly was because on arrival (despite having booked 2 months in advance) our table wasn't ready and we had to wait in the bar/reception. This area was absolutely packed to the extent that we almost had to stand in front of the front entrance. No apology was made for this and I really do feel, given the very high standards otherwise, this was a little bit disappointing.

This is a good restaurant, i only know the trattoria, in the first floor, is good but not perfect, the staff are very presumptuous, attention is not very good, are very slow, the wine is very expensive and there are only italian wine. The food is good, but the menu is limited. Reservations recommended before you go.
In spanish: Buen restaurante pero un poco caro, los camareros son un poco tontitos, un poco pijos, el más atento es el que parece el encargado, pero es el más pijo de todos, eso si, la comida está bastante buena, pero por el precio que pagas, no lo parece tanto, de todas formas, si tienes antojo, por Jamie Oliver, allí no estará, pero si vas, reserva primero.
Abajo el restaurante parece mejor pero no tuve aun oportunidad de probarlo, de ir otra vez, no volvería a la trattoria, iria al restaurante del sótano, eso si, muy bien vestido, es un local muy "pijo".

Had the Taster Menu for my birthday and it was stunning. Fantastic service, sat next to the kitchen which was really nice. Lovely evening. Would highly recommend. Wine list is very pricey but if you are out to indulge well worth it.
