So this is probably going to be a bit unfair but this is one of the few places I have been that it is really easy to compare it to one of their competitors (Soho Sushi Burrito).
Went here twice on my most recent Vegas trip. Loved it! Fusion places of sushi and Mexican are combining two of my favorite things.
Created my own burrito both times. Got the taro chips and cheese too each time. The biggest complaint I have was the taro chips really ended up being broken up into pretty small pieces. Otherwise everything else was really good.
Since this is almost identical to Soho I had a direct comparison. I thought Soho was slightly better than Jaburritos but Jaburritos has the convenience factor!
