Yo.. airport food. It's not supposed to be good (well, it should be, but in general it's not.. you get it), and this is no exception, but I was alright with it.
I got a bowl with rice, beans, veggies, hot salsa, and guacamole. It was all alright, only a bump and a hump better than cafeteria food. The hot salsa was actually a little hotter than a bell pepper, which was surprising to me. It had a decent flavor too. The guacamole was shockingly good: I got a giant splooge of it, it tasted fresh (even if it wasn't) and was really limey, which I'm always down with.
A little less than $11 for a burrito bowl at an airport is more than fair (one star.) I also didn't barf (another star), and I was full (the last star.)
There aren't many options after 9pm at the Vegas airport, but Baja Fresh isn't a horrible one. Think of it as a middle ground between Taco Bell and Moe's if the Mexican "authenticity" chain is Taco Bell, Moe's, Del Taco, Qdoba, Chipotle.
