I haven't eaten at Keisuke in a while. But his shop at Capitol Singapore (13 Stamford Road #B1-35) serves an iekei bowl that I hadn't tried yet, so I grabbed one while I was nearby. It was pretty darned thick, with a broth that was so sticky that it was more like a sauce.
Some prawn flavour, but not as intense and flavourful as I hoped or remembered it to be.
