The thing about those Turkish lentil soups was their inviting aroma - invariably, utterly irresistible and insanely enticing - rather than their (rather mundane) appearance.
Colleagues had recommended Turkish lentil soup - one going so far as to suggest that this (the lentil soup) was worth the price of admission to those fancy airport lounges.
I remember the first time I had one; I was en route from central Asia, over-nighting in Istanbul on the way home, and I was sitting by myself, sipping a beer, relaxing, outside a slightly grotty, rundown, apparently utterly unremarkable, small restaurant/bar.
It was twilight, a lovely velvet twilight, and the local cats were slowly twining and winding themselves around my outstretched feet.
Actually, this was a place that I subsequently realised was an award-winning spot, (it did have discreet awards, and I did look it up), and to which I returned, subsequently, on several occasions, where I was always remembered and welcomed by the staff, who learned - after a few conversations - just exactly where I was working - and in what capacity - at the time; one took me to meet some Syrian refugees who worked in a local carpet shop, and another time the manager invited me to join him over a hubble-bubble when he finished for the night.
Anyway, it lies in a modern side street in the centre of Old Istanbul; I was sitting, relaxed, sipping a well deserved beer, when my nostrils reacted with insane, delirious delight (and desire) to a bowl of vaguely muddy looking soup that was being served to a Muslim family at an adjoining table. I requested a bowl of that soup - it was fantastic - and it was served with stunning warm Turkish bread.
Anyway, anytime after that whenever I passed through Istanbul, I always treated myself to lentil soup, beer and amazing bread, usually in that restaurant.
