While some restaurants have increased the prices stealthily, this one has done the other way round. The set price is about $15++ to $16++, which was used to be about $22 to $24++. Then, the food, of course, is served in a smaller portion, but it is acceptable. The refill (of miso soup and plain rice) and ice-cream for the set is no more available. Click
