My menu looks really funny

Hi,

The menu on my site https://bankruptcy-in-montreal.ca looks terrible and no matter what I try I can’t get it to look right. I would appreciate if someone could take a look and see if they can point me in the right direction.

I was using a previous theme and changed the theme, could that be causing some issue with CSS being left behind from my previous theme?

Thanks!
