Beer : When In Rome

This is a beer in Prague. When in South Africa I had one of theirs. Same with Belgium, Spain, England, Scotland, Italy, Ireland, Germany and elsewhere. At a Thai Restaurant it is Thai beer, and same when eating in other places. I need the ethnic or local beer. I am not a big beer drinker. Just one beer in most countries. But, it is fun to try the local brew. Czech beer is good.
