During my Baja adventures throughout the years, I've had a change to get to know almost every…read moreenclave in TJ. This includes Zona Centro, in which this shopping plaza sits.
This place is similar to swap meets/flea markets that you'd find in downtown LA and at the Roadium. They sell a variety of items, to include cell phone accessories, shoes, clothing, and nickknacks that one would take home as a souvenier.
There are two levels to this place, and it is the same building as Plaza de la Mujer (which has nail salons, hair salons, and such). On the second floor, there is a coffee shop (D'Volada) which sells decent coffee and pastries, as well as sandwiches. There is a restroom upstairs as well, just make sure you bring some pesos in coins, else you can't get past the revolving gate. There is a small playground, if you're travelling here with kids.
Despite the area, this place is actually safe. I've never had issues the few times that I've ventures here, and the workers are friendly and helpful. I've bought stuff here, and the quality is comparable to the price.
If you're looking for upscale only, then stick to Zona Rio and the Hipodromo. But if you want to venture to a locals spot, this is one option. Cheers.
