North Indian food...not available.
Hiring a cook...if you are single and want someone to cook only in the evening, the cook will charge you more than the cost of food for the month...:)
Tiffin Services...heard of one but wouldnt recommend to use as food quality wasnt good, as told be the people who used it.
So you are left with self cooking. Cook in the night, eat, save in fridge for next day and warm and eat...:) Or shift to Arabic food....I was exactly in your position, hired a cook for a while but couldnt handle his tantrums and so moved to Arabic food and now dont have much problems as before cos of outside/ hotel food.
