I second Sweden Laundry. Also Secret Garden, Rooftop Prince and Love Shuffle.
I liked 'A Gentleman's Dignity' and 'You're All Surrounded'.  Not typical rom-coms, but some very funny parts.  
Why not try Thai? Cast look good as well, with available eng subs, and really funny. Check eng sub trailer on Youtube
