Bedford Farms (in Bedford next to Holi, and in Concord Depot adjacent to commuter rail station) has really dense ice cream in huge servings, and serious Frappes (no coffee drinks though.) Window service in Bedford, indoor counter service (and bathroom) in Concord. Only a dozenish flavors, with some New England standards like Green Monster and Moose Tracks. (Concord location also has a freezer with prepacked icecream and icecream cakes - they'll pack pints on the fly too, but it's good for picking something up on the way to a party that'll stay frozen.)
If you're picking something up for me: Moose Tracks Frappe (fallback: Mint Chip.) But really, just ping me, I can walk there in 15 minutes :-)
