Many people don't explore Japanese food beyond the sushi/sashimi/ngiri axis. But with the advent of the colder weather, Japan's hot dishes might hold more appeal. Moshi Moshi - the mini chain that introduced us to the now familiar kaiten, or conveyor belt sushi - has introduced a new range, covering more familiar options, from gyoza (the squidgy little pork and vegetable dumplings) to a selection of donburi dishes (meats served with rice) such as teriyaki unagi (grilled freshwater eel with teriyaki sauce). Prices range from £5.50 to £6.50.
