Today I bought brisket at the store on Kamennaya Gorka. I am very unhappy with the seller's service. I understand that she needs to sell the goods, but why blatantly deceive customers? I do not recommend buying meat with a rubber skin there.
There is a similar store on Mogilevskaya Street.
Decent sellers work there. They will always advise you and do not deceive you.
And the meat is always fresh.
