Beef steak from Wow Wow West

I haven't had steak from a local western food stall in a long while. Chance would have it that I noticed someone eating one from Wow Wow West at neighbouring table and I thought it didn't look bad. It didn't taste bad. Just pretty chewy. The texture on the surface was unusually rough and for a moment, I thought their beef steak was a giant beef patty. But it's not.

The stall asked if I wanted 半熟 which I agreed to. No idea if that meant medium or medium rare but the meat turned out somewhere medium well. I kinda like the flavour imparted by the char on the surface and it didn't taste half bad with the sauce.
