As a restaurant, I think the first thing someone would want to know is the location and timings. This way, I am not in agreement with danleveylibaton53's comments (though I do agree that too much of text in the main page would be a little distracting). I would suggest that you place your address and contact number as part of the footer (since there is sufficient space).
I agree with the others on the theme. Since you are using Joomla, changing the themes should not be a big effort. Here is a link for you to look at - http://www.brighthub.com/internet/web-development/articles/76718.aspx
