Help me create an itinerary

I am originally from Lucknow, but had shifted back to Delhi in 2017. I am taking my friends for a one day quick getaway to Lucknow. We will reach 7 am in the morning and have a return bus at 10:30 PM. I’ve so many places and cuisines crossing my mind that I am so confused where I should take them. Help me plan an itinerary to maximise the fun in the limited time that we have.
