I agree that it looks a bit like a blog, but only insofar as it has superfluous info like ‘Date posted’ and by who - and comments (do you really want to be constantly policing comments?). But I think it’s a great start with a very good look and feel. But I’ll be hypercritical for the sake of brainstorming…
I think the dark green background of the banner is a bigger problem than the black. I did a site once that was designed by a professional graphic designer that had a very similar dark green (all over). At first I loved it, but was really sick of it by the time I was done. Eventually, the whole company thought that the dark color was too heavy and overly dramatic - to the point of depressing - and we finally replaced it. As a first step, you might try a grayscale image of one of your pizzas (or something else - dough tossing, fired oven, etc.) and superimpose a transparent green rectangle over it and play with the color and transparency until you have a nice background for your banner. Then select a color from that graphic to re-use for a background color.
I would also make the banner less tall. On my laptop, it forces the featured content to run off the bottom of the screen. I wonder if you need to repeat the Pyramid Pizza name when the nice logo is perfectly clear as to that.
Hopefully, once you get your pictures up, you’ll be featuring your actual specials rather than links to them.
I would move your lunch buffet banner to the top-right and eliminate most of the other stuff on the right. Put the menu on its own ‘tab’ where you can provide a description for each item. As it is, the menu poses more questions than answers (e.g What’s a King Tut?).
Add a prominent Order Now link leading to a page that describes ordering options - even if it’s only a phone number. One of my first questions is whether I can order online. An ‘Order Now’ link will answer that (either in the affirmative or negative) quickly.
I like the brick background but you might experiment with blurring/fading the image to get the eye to focus on the content rather than individual bricks.
Large/Medium/Small - How big? Serves how many?
Google maps are seldom a bad thing.
Feel free to PM me if you’d like and I’d be happy to mock up some ideas gratis. I’m an under-contracted IT consultant who is entranced by the thought of opening my own pizzeria but am trying to resist the siren’s song. Better to use some of my free time to get closer to the biz rather than sitting around watching the Food Network.
