There are many Chinese shops in Juk-guk Texas Street. Among them, there is a shoewon gyoza restaurant where the outside is crunchy and the inside is chewy.
Looks like there are Chinese restaurant(s) nearby and Russian restaurant(s). Also there are bars. My hotel was nearby so walked around and did check it out. I did not try the shops or restaurants.
This is a back alley opposite Busan Station, and in the past there were many clubs for foreign sailors and US soldiers, and it was also a street that Koreans did not want to enter.
Now more and more restaurants, accommodation, currency exchange and clothing stores are here. There are more and more Russians.
Personally, I like the atmosphere of this street. But I recommend coming during the day and heard that it was a mess at night.
