Out of the usual activity of shopping, eat and sightseeing, robot restaurant sure give a different experience in Japan especially tokyo. The show is around 1 and half hours. Though there are around 2 to 3 times break that take about 15 minutes or so for each break. Just thought that it's a bit too pricey, around 8000 yen for walk in visitor. Luckily for me I purchase ticket from traveloka with discounted price. Also get souvenir but only a ballpoint. 1 time visit is enough for me personally
