good casual veg eats between West Hartford and Boston
Sorry, coastal....Pawtucket is not on the drive from Hartford to Boston. Unless you make a really long slow journey via RT 44 and 6.
I-84 to the Mass Pike to Boston is the usual route. and it is worth a 15 minute detour to Belmont Vegetarian Restaurant in Worcester, MA
Being a major college city, there are many good vegetarian options in Worcester, the link below takes you to VegWorcester.com's restaurant listing.
My nephew's wife and kids are vegetarians and they lived in Worcester for years, so I got to visit a number of these establishments.
