My picks for Disney Hollywood Studios are:
1. Mama Melroses
2. 50PT
3. Hollywood Brown Derby
I haven't tried Sci-Fi because I'd rather get on the boat and head over to Beaches & Cream at the Beach Club for a burger, fries, and ice cream....
I also agree with Belleatheart, avoid H&V. We went right before the changeover to the character experience, but the food and service were horrible. The food was so bad that we actually left hungry. I got a little bit of everything, and tried tasting little bits of each. Even the desserts were bad. The "food" was cold and tasted like it had been sitting out all day.
As for ABC Commissary, we have been there many times, but we always get the burger and fries, and it is... a burger and fries... I'm not sure what ppl are getting that is disgusting (although as I recall the menu, some of the things up there didn't look very appetizing as a quick service meal)...
