The recommendation engine takes into account the choices made prior to the current meal before making a new recommendation. You are seeing the "Looks like you selected a combo" message because someone else made a selection using the hacker account and the app will not let you select multiple meals in the same time period. This will not happen if you created an account for yourself.
There is a FAQ link in the app that addresses some of the issue you brought up and we are working on incorporating the rest. As of now the only way to go back to the home page is to hit the log out button.

Why not simply link the logo to the homepage? That's an affordance that every other web app in existence makes, and it was pretty surprising that you don't even have your logo linked to anything.
I can click through restaurants and menu items, but there's no indication as to what is actually going on. Tooltips pop up randomly, and if you can manage to keep one on the screen, they give you a paragraph that doesn't actually explain what's going on.
There seem to be star ratings that you can click on to rate things, but clicking them does nothing.
Eventually I clicked "Select" on something, and it popped up "Looks like you selected a combo" in a javascript alert box. Was that an error? Confirmation? What next?
If I could make it back to the homepage, or to some form of documentation, maybe I could find out. But I can't, so I left.
