At my company, we are connoisseurs of fine roast beef. We have a ""good list"" and a ""great list"", and Royal House is at the very top of the ""great list"". Simply put, they have the best roast beef sandwich in northern MA. The sauce is out of this world, the bread is always fresh, and the roast beef is warm and tasty. They also have great McDonald's-style french fries, and one of the best Greek salads around. We also love the pizza rolls and spinach rolls. Their location is just one minute off the highway, and we happily travel 25 minutes each way to go there when we want roast beef.
Pros: Perfect food, great value, easy parking.
Cons: it's small, and can get crowded at lunch time
