A no-frills southern Indian restaurant, Ragam is in the shadow of the BT tower.
No romanticizing this one - it's not particularly pretty, but the food is pretty spectacular. Dosai are delicious, as are the curries and breads. You'll be satiated, with taste buds thrilled, for less than £1o each. A rare thing in London these days, and great if you crave respite from the frenetic over-subscribed trendier restaurants in town.
