I've been here many times. I always bought something. The price level is different. There are normal, reasonable prices, and there are from the category of fiction.
What I didn't take there were fruits and vegetables. Prices are highly inflated. It is possible that the quality is high, but my income does not allow me to check it.
In general, I recommend it
While I was in Chisinau, I went there every day. I really like some boutiques, but I do not recommend fruits and vegetables that occupy a large area. The prices are expensive. Sellers are very intrusive. It is impossible to just look at them, they immediately rustle the package.
I have visited the Union several times.I really liked everything. I especially liked the store where they sell tea and coffee (alas, I do not know the name)! Very nice staff and awesome coffee!!!
