Just a quick post to say, "AM HOMESICK!!". I spent many holidays in Pana and practically lived there for most of my teenage years. Some of my fondest memories are and have taken place there. I partied at The Chapi, and went for 'chelas' at the Sunset Cafe. It all seems like such a long time ago. Thank you Eve! They are SO real and close to my memories and heart. :)
You can get the 'Champus' anywhere in Guatemala. I don't know where in the US you can get them, but if you look for a Guatemalan grocery store you might be able to get some. Sorry, can't help you more.
