Chrome for iOS has a similar look and feel to the desktop version that you know and love, so it won't look completely foreign.

On the iPhone however, you do not have the tabs across the top of the screen, but they're accessed through a tap on the top-right of the screen, which brings up your open tabs in vertically stacked cards that you can flick through.

Next to the omnibar (the combined URL and search bar) there's a menu button (three horizontal lines), which allows you to bookmark pages, access the settings panel and other features.
