Kilburn is as yet ungentrified - and as such, the customer base is still proliferated with the traditional hard core Irish, the Londoner of a particular age and mind set, as well as the young and upwardly mobile. Like with London itself, the mix here really works. Offering an untrammelled selection of gin, ales and bottled beers, this exceptionally warm and friendly old style British pub oozes warmth and charm.
It is divided into two sections: one with low seating - the other where the punter can sit at a high table and there are bar stools (with sensible attendant coat hooks) around the bar itself. The bar is well staffed and they do well to negotiate a tiny space to an often packed crowd. The food is tremendous, with the staples of Brit Cuisine on offer, well presented in nouveau style but without the customer feeling compromised in the seemingly endless pub chain practice of portion control. The Sunday Roasts are divine - and it is wise to choose this delightful gem against the less charming, more expensive and better known Black Lion or North London Tavern. 
There are music and quiz nights: Kilburn is massive in terms of still bringing home the live music bacon, even in a city where this essential ingredient to the city hubris is in danger of extinction. Note the steady erosion of Denmark Street. Friday, Saturday and Sunday nights at the Colin are for the fans of traditional Irish music, and Monday night is acoustic Open Mic night, where up and coming can flex their muscle. Rare is it now that a bar can be free of Sky Sport, let alone offer this much in a limited space. Check it out. A vital slice of proof that a disappearing London is still alive and often kicking somehow, somewhere to an appreciative crowd.

Lovely place, great vibes, good music and wonderful atmosphere. Also kind attention and good selection of beers.
