Help identifying a [Sufi?] Dargah in Old City

I'm just putting this post out there to see if it jogs anyone's memory...

Several years ago I was wandering without direction in the northern part of the old city of Varanasi when down an alleyway a radiant, seafoam green and light blue gem of Islamic architecture caught my eye. It turned out to be a small dargah, a tomb or other shrine with a small courtyard. If memory serves me it was north of Manikarnika Ghat.

It's not the most specific information to go on, but is there anyone who can help me with a name or something, so that I might easily find it again when I return to Varanasi? Many thanks.

I think its Alamgir Mosque at Panchganga ghat very close to the Manikarnika ghat.
