Patty,
If you need Baw-sten speaking lessons I'll be glad to help when you return! After 35 years away the locals think I have no accent anymore!
Don't know anything in Sommerville but almost any fish or Italian place is wonderful. The Irish places do "New England boiled dinner" that has corned beef, cabbage and potatoes. And of course you need a good lawb-stah too! Lawb-stah rolls are a good way to use hot dog rolls!
ENJOY!
Kevin
