Yup, this guy's english is perfect. He also speaks a bit in Can Love Become Money.
As for other dramas, I'd suggest another two: Sorry I Love You and What Happened in Bali. Both with So Ji Sub speaking english... and what a bad and random english this is! If it weren't for subs I'd never understand what this guy was mumbling about.
