NuGo has many gluten free bars. I recently tried the Dark Chocolate Crunch and NuGo Dark Mocha Chocolate. I found both of them to be good. NuGo Dark Mocha Chocolate definitely had a dark chocolate and coffee taste come through that I really liked, but it was strong so it's hard for me to guess how likely it will appeal to others. The truth is that you'll have to try some of these to see if any taste good to you, obviously, so give them a try and find one that you like.

Bars can be really important when you find yourself somewhere that is devoid of restaurants that cater to the gluten free diet, so do your research and find one(s) that you like!
