The lunchtime crowd at LOVE Park on Thursday noticed a few guys with videocameras milling around the Guapos Tacos truck.

If you ordered, you got an idea of what was going on: Iron Chef Jose Garces was making the tacos, while Dr. Mehmet Oz was taking orders.

The women in front of me got a gentle education on the merits of the chicken or fish tacos opposed to the short rib tacos they ordered.

Of course, I ordered the fish. Garces did an acceptable job assembling the tacos and they were delicious, but they're messy by nature. A napkin in the bag would have been nice.

A producer brushed off my questions about the shoot or tell when it would air on the Dr. Oz show. I have a feeling it's part of a piece on healthful choices.
