I don't know what you guys mean about Clif Bars not tasting good--the banana nut bread flavor is delicious. I also really like Luna Bars. Both rate highly for nutrition.
For a good guide to meal replacements, high_jinx, here is a link to a feature recently in Women's Health:

I go through about a box of Clif Bars every week and a half or so.
Kashi Go Lean bars are pretty good too.
