I've made a great discovery in West Bridgewater (the Route 106 West exit off of Route 24) - Montreal French Fries. It is located directly across from the Shaw's Corporate Offices, and has a decent sized parking lot.
This is definitely a no frills menu, offering 2 types of paninis, hot dogs, hamburgers (including a salmon burger), fries, sweet potato fries, and poutine.
The other stuff is pretty sub-par, but the real story are the fries. They use PEI potatoes, fried in peanut oil - they are thin, limp, and greasy, but oh so tasty. The poutine is great, and a unique offering in the area. Check it out if you're in the area - their hours are 11 AM - 8 PM
