Great place for kids and families. I came here on a visit to Juarez. I paid about $31 USD for 3 adults and 1 child. I paid with a US Visa card and it worked no problem. The museum is very clean, modern, and up to date. Employees are friendly and knowledgeable about science. I mainly spoke Spanish but some do seem to speak English. You will still enjoy even if you don’t speak Spanish, most of the signage is in both languages. Note: you can’t bring backpacks inside, but you can leave then at the paqueteria up front.
The food court is good, lots of choices. It’s 3 different restaurants: a candy/snacks shop, a cafè, and a deli/grill. They take credit cards there as well.
You could easily stay several hours here, we stayed about 2 hours. My 5 year old had a lot of fun and enjoyed herself.
