Cheapest place to live in Gurgaon? To eat healthy under budget eggs chicken

I’m planning to move to Gurgaon soon and try to keep my expenses low.

Food is a big concern for me — I usually rely on simple, cheap options like boiled eggs (~₹10) and budget chicken stalls, not expensive fast food or restaurants.

I don’t know the areas well, so I’d really appreciate some guidance:

Which areas have affordable PGs?

Where can I easily find cheap food / basic meals nearby?

I’ve heard about DLF Phase 3/4, Sector 21/22/23, and Udyog Vihar — are any of these good for budget living?

If you’ve lived there or know better areas for cheap PG + food combo, please share 🙏
