When I first came to Spain I noticed that people spend a lot of time outside, meeting people and having something to eat. In many ways, it is much more of an outdoor lifestyle than in the UK. I also noticed that many of the bars are completely “packed” (hasta arriba) with people and sometimes it is even difficult to get into the bar!!
The word “packed” is used when we see a place that is completely full with people and very difficult to get into. Most Spanish people don't know this use of the word because when they think of the word “pack” the first thing that comes to their mind is the verb: “to pack” which is used when you are “packing your suitcases” or “packing a present to give to someone”.
Hope that helps
