This place gets 4 stars for location and convenience. The menu is minimal--small for a diner. However, the food is good and the service is consistently good. This place is also very reasonably priced.
The atmosphere is simple very pleasant, especially for people who like watching the street: right in the middle of shaker square, situated right next to where the trains stop, this place practically IS the train station. When eating you can watch the trains and people come and go. I only wish the trains ran all night long like this place does!
