I have a group of six 20-something girls meeting for dinner on Friday night. They aren't especially adventurous and I'd like to keep the cost less than $15 an entree. The other factor is that 3 will be coming from Boston/Cambridge, 1 from Worcester, 1 from Framingham and 1 from the Cape. Any ideas about a good meeting spot that would be least inconvenient as possible for all? So this may be tough but can anyone help? Thanks in advance!!
