Ate here today at lunch w/ two friends - very friendly service and very reasonably priced at lunch.
Friends both had the thali, which at lunch is only £3.50 - includes 3 puri or chapati, pappadam w/ mango chutney, yogurt, rice, three veg dishes and a small salad and a sweet. Very good deal for the price, since it was a lot of food. The three dishes today were dahl, black-eyed-peas, and a mixture of eggplant (and some other vegetables, but I don't know what). The eggplant dish was, in my opinion, by far the best. Really tasty. The other two were nothing special. One friend requested a chickpea curry instead of the black eyed peas, and the nice waiter (and owner?) said this was fine. I didn't think it was any better or worse than the chickpeas.
Meanwhile, I had the masala dosa. It was good - and also priced nicely at £2.99 at lunch. Filling was fine, sambar was OK, dosa itself wasn't as crispy as I usually like, and I forgot to notice whether there is a different option for paper dosa, which I'd probably like better. But again, a good deal.
So, probably nothing to go out of your way for, but if you want some pretty decent good veg. Indian near Turnpike Lane, then it's worth a try. The owner is Gujarati, and I wasn't sure how much of a Gujarati influence there was in the curries - I don't know enough about Gujarati food to know. But I am quite interested in exploring the menu further, and it seemed like the owner would be willing to help point me in the direction of any house specialties.
