It is honestly easier to go to BNZ than to Aishbagh. It'll take the same time via metro for one to go from Lucknow Jn/Charbagh to Badshah Nagar as via road to Aishbagh [ in fact, faster since metro runs at periodic intervals vis a vis road transport to ASH isn't always easily available].
Ironically, the best way to go to ASH is to just follow the tracks. That is technically, the shortest route at ~1 km. I once had to receive a relative of mine from ASH and I just followed...
more... the rail route instead of waiting for a road route :p
please wait...Translate to EnglishMan, it's just easier to hit up BNZ instead of Aishbagh. Takes about the same time hopping on the metro from Lucknow Jn/Charbagh to Badshah Nagar as cruising by road to Aishbagh [actually, metro's quicker 'cause it's always coming, unlike the rare road transport to ASH].
Funny thing is, the fastest route to ASH is just following the train tracks. Technically, it's only about 1 km. Had to pick up a relative from ASH once, so I ditched the road and just stuck to the rails :p
