Continue by train to Masjid Bunder for a quick transfer into the old-city atmosphere, then explore the bustling lanes near Crawford Market. If you want a snack break, stop at Britannia & Co. for a classic Parsi-style bite or sip a cold drink nearby.
Take a short train hop back toward Churchgate and unwind with a calm stop at Hutatma Chowk and the nearby art-deco streets. This is a good window to browse a few local shops or simply watch the evening commuter rush begin.
