We drive to Escazu almost every weekend, just to go to Hiper Mas. They have pretty much everything we need to stock our pantry and more. The other commenter mentioned that there are "huge crowds", but I've found that it depends on what day and time you go. We can usually, get in and out really quickly. If only the had another location a little closer to us.

The Hiper Mas is just like the Super Walmart back in the States. They have pretty much anything you need and discount prices. For warned, If you go shopping here, expect a huge crowd.
