I've just moved in hyderabad and was looking for something good which doesnt cost heavy on my pocket either.A little googling and lot of experiements finally got me to Aha Foods. Run by very nice and polite guys they truly care for your likes and send you North indian home food ( as their website says) for lunch and dinner. I've already forgotten my ghatiya office canteen food.
You can get their details on www.ahafoods.co.in, or call them at 9393525330.
Best Wishes
