Good day,
I have been designing/developing websites for over 20 years. I am happy and interested in this project.
I'd suggest creating this restaurant website based on WordPress platform which gives you power and full CMS features along with the ability to add or change things including content management.
For the mobile side, I can provide it for you based on Android app which communicates with the website as necessary and/or have some offline features. I can also register it for you on google play.
As a free addition, I will make your website SEO ready.
As a free addition, I will submit it to major search engines (goodle, yahoo, bing).
As a free addition, I will link your website to social networking websites.
As free addition, I will provide you with technical support for 2 months after this project finishes if there is a problem happens.
I need to know more specific details about this project so we could have some discussion about it.
Thanks and best regards,
