San Miguel de Allende in Mexico comes to mind. Oh, it’s definitely very Mexican, but there are so many Americans that nearly every restaurant has an English menu, and many of them have prices in US dollars. It’s actually such a nice, lovely town that I would consider retiring myself there someday. However that’s in spite the Americans, not because of them (unlike Nava’s first example, I’m actually quite fluent in Spanish). On the other hand the Americans drive the prices way up, so it might be a better idea to look for someplace less invaded.
Shanghai is where I go when I want to escape to the west (I live in Nanjing). The first time I visited my dentist in Pudong (better service than I can get in Nanjing) on Hongfeng Lu, I was amazed. I felt like I was in Ann Arbor, Michigan. And of course in Pudong is Kerry Parkside, which also feels very non-Chinese.
In general (for this thread) in Nanjing we don’t have a Americantown. However there are so many western foreigners from many western countries, and we fall into three major groups.
University students assimilate best. They either live in dorms or with roommates, and like most college kids they don’t have a lot of money. They tend to eat at local Chinese low-cost restaurants.
Then there are English teachers. The ones I know tend to mostly stick together, but live in Chinese buildings where the rent is low. A surprising amount of them don’t know Chinese and aren’t interested. They hang out at expat bars and restaurants which aren’t really in a single zone, but spread throughout the city.
Then there are us corporate guys (and gals). We do tend to congregate in three or four different neighborhoods, centered about the two major foreign schools that are in the city. We don’t assimilate because we’re expat workers, not immigrants. I’m okay with that, because we work long hours. I get frustrated by the spouses, who have a great opportunity to experience culture, but instead most of them form social groups that specialize on making fun of the locals. We tend to go to the high-end Chinese restaurants, or especially the expat restaurants and bars.
I guess the only thing close to Americantown, then, are the two international schools. Well, one is the British school, so I suppose it’s more like a Brittown.
