Website looks terrible on iPad/tablet

Hi, my new website looks fine on mobile view/iphone and desktop, but when i checked it out on my ipad, it looks a little off.

Firstly, its showing the hamburger menu, can I change this? I think the ipad screen is big enough to show the desktop menu.

Secondly, the page doesn't fit on the screen, its too wide, so there is a horizontal scroll, almost likes its zoomed in, but you can't zoom out.

Thanks

Are you using custom CSS? It looks like something is changing the tablet view, like the site is caught between desktop and mobile. Tablet landscape view should look okay, but I know that is not the solution here.  You may be able to force the site to stack blocks with larger screen than mobile.
