Menu Stretching

Is there a way to stretch the menu so menu items do not wrap? My client has long named pages (e.g. Temperature Controlled Warehousing) and the menu items are upper case and wrap and are sometimes hard to read. Is it possible to have the menus widen so that they can contain the items on a single line? I’m sure I could do it with some custom CSS but I was wondering if there is an option somewhere that I can use to make that happen.

Thanks for your help/insight!
