Gyudons from Yoshinoya

Yoshinoya has come up with a few variations to their beef bowl lately. Here's a look at their tamago and rutan beef bowls which features a half boiled egg and a hard boiled version respectively. The egg from the latter was only briefly stewed in sauce.  Not much of the brown was on the surface.

While I'm not a fan of these guys I've to admit that there aren't anyone place else I know of that makes a savoury gyudon. Without sweetness in the sauce. With the egg in the bowl, I might just start dropping by again.
