if it was just for the quality and value of the food, I would give hana a solid 3 stars. it's really not bad. there are some interesting items and everything that I had was fresh. unlike others, I didn't have to wait particularly long for anything.
although you mostly interact with the tablet, the human service was fine. having been to similar places before, I did find the tablets a bit laggy.
anyway, the place is unique and a blast for kids. I give it an extra star just for the trains.
