Here is the URL for the Globe newspaper's dining reviews. This one has a review of Dim Sum at the Chau Chau City -- a challenger to the best in Chinatown.
Read the review and see what you think.
If you go into the Globe dining archives you can find a lot of "cheap eats" places with fine food. However -- time changes things and some places are not what they used to be. Some have sliped away -- like the wonderful little authentic Singapore place that was in the South End. Call before you make plans.
