I've killed a couple bears, the meat tasted decent to me (better than deer, IMO). My complaint was that it was awfully tough, the only way I could chew it was to grind it up or simmer a long time in a crock pot, until it basically fell apart. I would think if a bear has been eating fish, garbage, or road kill, the meat might be a little rank tasting.

Like many things, I guess it all comes down to personal opinion.
