There's a small roll place in Khan Market corner (not Khan chacha ofc) they are not even expensive and have a great variety too
chowringhee lane, satya niketan
Juneja's CR Park Market No.1, They serve chicken rolls in Butter Naan/Parantha. Should defo try their Butter Chicken Roll and Malai Tikka Roll.
Khan chacha, al bake, chowringee lane, rolls kings
I think Khan chacha would be best among all roll corners.
