Lahori Karahi (Southall - 777 London Rd, Hounslow, TW3 1RS tel. - 020 85773344) is by far the best in SW London. They do REALLY spicy curries, and I have personally had the vindaloo, and it is HOT!!! They are so nice in there, but they don't serve alcohol, so if you want some you can bring it, or buy it in the convenience store 2 doors down. They are happy to provide glasses and a corkscrew! x
