I've been to Bolt twice now. It's a good spot to grab a quick healthy bite. The bowl servings are very generous. Being a meat eater, I was still full after finishing my quinoa bowl. The downside of this is the salsa mysteriously absorbed into my meal and left it seriously lacking taste. I had the protein bowl the second time and the dressing + butternut squash give it more flavour - I'd recommend this if you're not making your own. Although, it still had a very "carby" feel to it I often get after eating vegetarian food. I tried the beet juice which was tasty, but a smallish serving for the price. The best part about bolt are the acai bowls. I've had both on the menu, and they are like a healthy dessert, although I question how many calories they have. That's how good they are!
Bottom line is a decent, convenient spot to grab a very healthy, quick meal. Think IQ/Kupfert/freshii but not limited to food court hours (aka no weekends).
