I like the idea of a website builder for restaurants because the majority of their websites suck - they're either flash OR they want you to download a PDF. However, there are a lot of competitors in this space such as:

http://www.happytables.com/ - who are using a Wordpress Backend which I'm pointing out because

http://en.wordpress.com/restaurants/ - Wordpress are offering designs for Restaurants as well

http://www.restaurantors.com/

However, I noticed that you actually launched on HN, 192 days ago - https://news.ycombinator.com/item?id=4483473 - which I'm assuming didn't give you a massive uptick in the signups that you wanted which is why I have a few suggestions:

First of all your website is a little bare, I would add more content etc onto the site, with additional pages etc. Likewise, I'd also make it clearer that you can click on the tablet etc to view the demo restaurant websites as well.

Have a look at your rivals (some of who I mentioned above) and you can see that they all have a considerable amount of content on their websites which encourage non-technical users (the ones with 100 toolbars on their browsers) to trust them more than you.

Likewise, you don't really have what I call an “Effective SEO” plan in place so you should start to get this going as quickly as possible - some of your rivals have been covered by high authority websites as well meaning, you need to get this started ASAP.

The “Effective SEO” plan goes back to the earlier point about lack of content on your website as well, which is something you definitely need to add. Once you have done that you need to focus on the following:

- Advertising & Partnerships With Sites In Your Niche

- Off-line Marketing (inc. word of mouth & traditional ads)

- Bloggers & Other Webmasters Within AND Outside Your Niche

- Online Communities e.g. Relevant Forums etc

- Social Media Channels - Twitter, YouTube etc

- Capture Future Leads (Newsletter Subscribers etc)

- Effective Site Branding
