Kelly's is the best for roast beef sandwiches, whole belly fried clams, and lobster rolls [expensive but definitely worth it to splurge once in a while!]. I have been eating there since I was a kid [I was born in Lynn, Mass.] and now still make the drive from Pa. to visit family and eat there every few months. They have numerous locations now- check their website: www.kellysroastbeef.com.
Sorry to hijack the thread- I just got excited when I saw this! Steve
