At the risk of getting beat down I totally disagree. I think the logo is awesome. The branding hit me in the face hard. "Chomp"? Yep, that looks like a chomp. :) I wouldn't change a thing. It's colorful and communicates the food message quick and cleanly. Having just the logo text by itself would be too plain IMO. As for higher scale restaurants, I don't think that's a problem either. The site won't be seen by their customers, yet it's fun branding any restaurant owner can remember.
True, and you can always change your logo later if you change your mind. Many companies alter their logo down the line, but my first impression of your site was very positive.
