Quoted from dmarston:The overflow hotel in Westford is adjacent to the retail portion of the Cornerstone Square complex.
Cornerstone square is fairly newish, only being completed at the tail end of my years as a Westford resident. That entire square has a lot to offer. There's a breakfast diner, pharmacies, I think a Whole Foods now, multiple pizza options, McDs, and of course a Dunkins where you can stand in line and look at another Dunkins.
Fun fact about the fast food though - Westford has a large "stuck up" contingency, and because of the easy 495 access to that square of shops, many didn't want the fast food bringing in the "trucker crowd" (this is what I was told my my neighbors upon moving there). Therefore, there are rules for the fast food places in order to operate - 1) No drive thru's. 2) Wooden siding if a standalone unit. 3) No neon signage.
Going in the other direction from the hotel also gives you some very good options. Bamboo is equidistant from the hotel as Cornerstone Square. That was my go-to for takeout.
Fuse Westford has awesome upscale burgers (their Crunch Burger for $11 may be the best burger in the region IMHO).
Nashoba Ski Area has the Sunset Tiki bar which is a cool outdoor atmosphere where you can kick off your shoes hang out in the sand, play cornhole, listen to live music. A bit pricey on the drinks.
Kimball Farm has the best damn ice cream, portions which illustrate why other countries look down at us, some of the best mini golf I've ever played from both a challenge and landscaping perspective, a driving range, batting cages, par-3 golf course, (*cough* pinball-less arcade *cough*), and more.
Keep going past Kimballs and you can cross the highway in Littleton where they have a huge new plaza with even more restaurants and a giant cinemas.
There's a LOT around if you're staying at the Westford Regency.
