Submenu Link Text Size Too Big

Hi, my submenu text links seem to have gotten bigger and I can’t seem to make the text smaller

Please see here: http://www.golfinhongkong.com If you scroll over the GOLF COURSES link on the main menu, you can see the submenu drops down, but then displays the links horizontally, and the text is very large.

I built another site http://www.kunminggolf.com where the same GOLF COURSE main menu link drops down fine and with the size I want.

I thought I built both menu’s the same and pretty sure I didn’t do any customisation on the golfinhongkong.com menu so am a bit stuck.

Can anybody help get the submenu smaller, and dropping done properly, like the one on kunminggolf,com?
