This place and market is too crowded. But it is a very interesting "mercado" to visit in Mexico City.
The amount of different types candy is amazing. One can find great variety oof Mexican candy and from different regions of Mexico.
If you like sweet and candy, this is a place to know.
Be ready to walk as it will not be a good idea to get there by car (driving) it would be better to arrive there by subway, taxi, bus, or even walking
Prices are moderate and, again, if one likes candy this is the place.
