Suggest accordingly for an intern. Preferably available on Zomato but in-person works as well.

Aswaad in Dadar West, Ladu Samrat in Lalbaug (if you are around the Dadar-Lower Parel belt), Araam Vada Pav (also serves Puri with Shrikhand and other Maharashtrian dishes) opposite Mumbai CST station.

Hugeeee Bump to Aswaad! Went there with a friend and really loved it, not exactly cheap but utterly delicious Marathi food!!!!

Paramesha Sandwich next to BSE (town)
Ayub's near KalaGhoda, Fort
Prakash (Near Dadar) for homely Maharashtrian food

Ayub's is expensive. Costs atleast 280-300 for a chicken roll. Too overpriced.

Have food from HC canteen

Ayubs is expensive asf bro.

Milan Lunch House in Fort. Poornima Lunch Home is also close by. Both are near HC Building

Best recco. Poornima is like home-cooked mangalorean veg food. Hygiene+Taset- 10/10

Baghdadi Restaurant

National Hindu - below JSA office in Ballard Estate Fort

Been here a bunch of times. Can confirm is a great place to have lunch intern-wise.

Was interning at JSA - food and snacks were too good, partners also often came down for snacks

Fort Deluxe - amazing Kerela food especially their sadya

Local Daba walas sure for cheap offers varities that may start from 90 rs for each meal. Contact them
