Considering about 50% of web viewers (as of Decemeber but dropping fast) are on 1024 resolution I don't know who else you would target a website for. You can design up to about 960px wide, which is generally the agreed upon standard these days, and is the size of almost all mainstream media sites, give or take a few pixels.
That being said, the Red Lobster site is only 850px wide... so they are neither designing for the 1024 crowd nor the 800x600 crowd, but instead lost somewhere in between, which is kind of fucked up.
The steaming crayfish tail (that's no lobster) they've got pictured there is cool, but overall I think that while it's a decent site, it's a pretty average decent site. It doesn't make me go "holy shit that's an amazing site!".
I posted a pretty extensive list of awards sites and site galleries previously here:
