if you have less money in your pocket and wish to fill your stomach go to ghar ka khana or if you want to feel good that you have eaten food sans the masala.
Low on cost, but decent on hygiene. You can try the parathas here or a roti - veg combination. The rice rajama/dal/etc etc combinatins are decent as well.
Try the lassi as that could turn up the high point of your time spent here.
