If you can't find the exact type of offbeat gyoza flavour combination you're looking for, create your own at this cozy Shibuya dumpling bar, opened in December 2017. Their 'deco gyoza' menu lets you decorate your potstickers with ten types of sauce and 18 different toppings, including coriander, grated cheese, cayenne pepper and mayonnaise. Their customisable lunch sets start at around ¥600 and are well worth exploring.
