I had a six pack of Bao today and it was plenty to fill me up. It cost less then ten bucks so the price isn't TOO bad.
I would give it a 3.5/5. The main reason I deduct points is because they don't stuff it enough with the filling. If they made the bread skinnier, I would go there every week but the loading of carbs with not even filling didn't please me too much.
I would still recommend trying it out, its def different than most of the things in the pedway
