This is a fun place, I used to work in Lynnfield and would head down there for lunch once in awhile....for those that have never been to a Fuddruckers, they have an enormous "toppings" bar where you can double, no triple the calorie count of your burger -- all sorts of toppings. And the onion rings are pretty good too.
Right near a Barnes & Noble & Home Depot so you can get your shopping done too...
