The best tapas I have experienced. The food is just stunning. Our highlight was surprisingly the anchovies and the amazing pesto that they came with. We managed to get a walk-up without a reservation at a table near the bar. It is an intimate environment that is set up for tables of two, although there is one larger table. I used to love the previous Pichos business, but in terms of taste Purnell's smashes it.
They were also able to adapt a good portion of the menu for a gluten intolerance and they had amazing gluten free bread.
One criticism - the jackets we were wearing needed washing as they had picked up a really strong oil smell from the kitchen that persisted the next day. I don't know whether anything can be done with the ventilation, although this won't be a problem in warmer weather.
