Chahan from Keisuke in Singapore
Here was the chahan from Keisuke. I liked the abundant smoky oil aroma, and they provided pretty generous chunks of meat in there too. I seem to remember liking Ohsho's version even more, but it's hard to say that given that it's been a while since I've eaten there. This was a worthy contender either way, especially when it's only S$6 (US$5).
And I'm glad that at least Keisuke's shoyu ramen survived the shop's menu overhaul last year. With that new order form that they have, it makes it easier for me to tell them to make sure my noodles are cooked extra firm, with the bonus more of that lovely oil on top. It just goes so well with that soy sauce and bonito flavor combination underneath.
