Although this pub is not a listed building, it is on the Campaign for Real Ale’s (CAMRA) Local Inventory as having an interior of Local Historic Interest, and the description is as follows: "Small two room pub with two external doors, with external brown glazed tiles on the ground floor. It is a late Victorian three storey building in a range along Kilburn High Street. It is a former Watneys pub with plenty of inter-war fittings, including an island bar, good quality fielded wooden wall panelling, dimpled leaded glass windows (including a set at the rear of the bar leading to the tiny “beer garden”) and a cast iron fireplace in the left hand bar. There is a baffle by the right hand door, but this looks to be a later addition. The two bars are connected at the rear of the servery via an archway. It is possible that the left hand room was the public bar and the right hand one the saloon as evidenced by the quality of the fittings in both rooms. There are small tables and seating along the walls. It remains a traditional Irish pub as befits its location in Kilburn."
