I understand that if you are an expat, you can sometimes miss something from your homecountry from time to time.
But as a tourist, even for 3-4-5 weeks, I will always eat local food.
Well, first time I was in Thailand, after 3 weeks with only thaifood, suddenly I needed a big dirty beef, but my stomach got crazy and was in double size for 2 days. Since that time no way.
