Igloo is a WordPress theme for restaurants that allows you to display your menu (food or drink items), photo galleries, your customers’ testimonials and any announcements you might have, mostly by using four different Custom Post Types: Slider Items, Menu Items, Galleries and Testimonials.
All the above act as standard WordPress posts or pages but each of them has extra fields which differentiate them from the former. The homepage is comprised of custom widgets specially crafted to bring those custom post types together as discussed later on in the documentation.
