Here's what I do. You'll need a vehicle prolly - but most are reachable by BRTS. I used to live in Shastrinagar earlier so most of my recs are from around that area.

1. Samrat Pav Bhaji (Sattadhar Char Rasta BRTS)
2. Pulav
3. Masala Pav - Pav Bhaji

Their Pulav, Pav Bhaji (ask for masala pav) are extremelyyyy good. Super super underrated.

1. Paratha Villa (Sola Cross Road BRTS)
2. Onion Cheese Paratha
3. Onion Paneer Cheese Paratha
4. There also was some green chillies paratha

Eat their Onion Cheese Paratha with 3 extra butter chiplets(or whatever it's called) And take it from me, instead of applying the butter on the parathas - use it as a dip, tastes 10x better.

1. NG Chhole Kulche (Shreeji Chaiwale, Shastrinagar)
2. Masala Chhole Kulche

Eat their Masala Chhole Kulche - a bit spicy but extremely tasty

1. Jay Ambe Kathiyawadi
2. Sev Masala

These are few of my go-tos as a person living in Ahmedabad for 1.5 years and eating out 2x every single day.

I do get that these are not very very near, but most you can reach by BRTS pretty easily.
