I wish them well. My wife and I used to be regulars there around 1999-2001, when we lived nearby. Returning to Chicago after several years away, we eagerly stopped by last summer--and were very disappointed with the quality of the food.
We noticed that the handsome young Vietnamese husband and lovely Laotian wife that used to run the place were gone. The folks now running the place claimed that they were their relatives (cousins, I think), and that the couple we were thinking about had moved out to the 'burbs--and I think they said the husband had gone into IT work, and his friendly wife was busy raising their kids (she was working-while-quite-pregnant back in early 2001).
Anyways, I digress.... I imagined that the food had suffered due to the new management, even if it was still within the family. Of course, my wife suggested that *just maybe* our dissatisfaction could have something to do with the fact that during our time away from Chicago we spent three months in Vietnam, getting used to the real thing....
Haven't been that impressed with Hai Yen, either, but hey--at least they have a version of Bun Cha (called "Bun Cha Thang Long") that begins, but only begins, to resemble
Hanoi's glorious dish. Now, if we can only get a dish, somewhere, that begins to resemble the almost equally-great
Cha Ca....
