Atomic Burrito is a tasty, quick burrito joint. It's like Qdoba or Moe's in that you can tell them what you want on your burrito. The cool thing is that they have lots of options for your type of shell, type of rice, salsa, meat, etc., with some really interesting things to try. I once had a pulled pork burrito with a watermelon salsa, coconut rice, and otherwise normal toppings. Although I'll probably stick to a steak or beef and less fruity salsa next time, I love the fact that they have those options. I have been there a few times, and some of these salsa and rice flavors change, which is also nice because you can experience different ones. If you order the steak, though, be ware because it is a lot spicier/hotter than I expected. I definately had to drink a lot of water.
As far as taste goes, I think it is better than Qdoba, but not nearly as good as Moe's (which unfortunately has not yet expanded to Charlottesville). Although it's a little small, they often have bands on weekend nights, and it's a nice atmosphere.
