Err... I'm French, and I don't know who taught you that, but personally I've never heard "Je peux aller à WC?". It's not quite correct, it would be considered as "beauf", as we say (and it's not a compliment, it's more like... like Dudley talking).Originally Posted by HPobsession
The best translation would be: "Je peux aller aux toilettes?" It would be the most common and most logical translation.
