Who writes the review? Staff or passers by? The most obvious way to create a community would be to seek input from the audience – especially for a review site. Ordinary consumers write the content for you for free, and they naturally feel attached to the site where they've contributed.

For now, your site seems rather thin on content. And I didn't see anything describing who you are, what you offer, or why your site exists. To build a community, you ought to build an identity first.

I'm not smitten with your brand name / domain. That's my professional focus, in case you have any questions in that area. A more authoritative and memorable name would serve you better with your twofold audience of readers and businesses.
