The Cow is probably my favourite pub in London. A typical Irish pub recreated by Tom Conran on the ground floor with a few tables at the back (and a proper restaurant above it). The crowd is different from the Westbourne, more “trendy local” and less flashy than the Westbourne. The location facing North makes its small terrasse less attractive but there is always a lively crowd around the Cow and lots of activity at the bar where the two most served beers are Red Stripe and Guinness illustrating the mix of Irish and local Carabbean cultures. The menu is small but go there for the sea food, the even have a great sea food platter if you are really hungry.
The restaurant above is small but excellent with a great atmosphere and a menu that changes regularly. Booking essential and it is probably quite expensive too (say £45 per head).
