They have 東山小小外語通 for 6+ children and 『創意英語話劇工作坊』 -- 適合小一至初中 .
And maybe you can try SpanishWorld at Central too. Last time I visited it on their open day and found it quite good. There are more items relevant to Spanish within the classroom and even a projector, which means children can watch videos (to sing songs) without hurting their eyes. The teacher (a female) is nice too.
