EV Trianing Pikachu Help!

[GameCodeTrainer]

Where is the best place to EV train a level 59-69
Pikachu? I gave it a macho brace, right now I want
to raise it's SP ATK and I read somewhere that the
best place to do it is in the Old Chateau. But I
only get a little bit of experience points at a time...
Is there a faster way to get experience points quicker
so my Pikachu can level up faster?

Go to Route 229. Roselia are the most common Pokemon there (40% chance of showing up).

And please, use the Simple Questions thread next time (I'm not a mod, but...)

EVs are not actually related to how fast you level. I feel like you might spend less time EV training in the Old Chateau and then leveling the rest of the way later, since everything there gives you special attack, whereas Roselia will only show up sometimes.
