There’s budget dining & then there’s Sagar, the ridiculously affordable trio of southern Indian vegetarian restaurants. This modest London group has achieved something close to cult status among students & indeed anyone feeling the pinch. The no-frills surroundings don’t exactly inspire reverie, but the lack of show is part of the charm. Expect decent, dependable regional dishes including idli (rice dumplings), dosas & uttappams (lentil ‘pizzas’ with spicy toppings) joined by a full quota of veggie curries, fluffy rice & home-baked breads, best enjoyed with a Kingfisher beer. For unbeatable value, settle on the mini lunchtime thali (£4.50) or pick up one of the unbeatable takeaway lunch boxes (two veggie curries, raita, rice, a paratha & a tiny salad for just £2.95).
