Speaking of gyoza, we recommend Ginza Tenryu (Ginza 2-6-1 Chuo Ginza Building 1F), which has plenty of volume. When it comes to lunchtime, it is a shop with a constant line.
Especially recommended is gyoza rice (it may be a little more for elderly people). 80% of the people will order. The skin is thick, but it tastes crispy and sticky, and the inside is juicy. The price is reasonable and safe for Ginza. This is a recommended spot where you can feel free to drop in.
