Where should I eat my first hamburger tomorrow?

I'm on a diet and fitness program. I've been doing the P90X exercises and really trimming some pounds. After I hit a plateau last week, my brother (a fitness trainer) put me on a diet regimen. For the past six days I've had nothing but six protein shakes. I've really cut back on calories, and I lost 7 pounds this week. I'm pumped and I'm also looking forward to binge day. We all should reward ourselves every now and then, and I do it once a week. Tomorrow I'm going to Burger Tex for my second hamburger. At the same token, I can't decide where to have my first. I'm not going to McDonald's because their food has no substance. Burger King is out, too. If I'm going to spend good money on some artery-clogging food, I want to make sure it tastes good. Hence, I can't decide between Wendy's, Sonic Drive-in, Dairy Queen, Jack-in-the-Box, and Whataburger. Which of those five places would you eat a hamburger from if you were me?
