I've had many all over the place. I still think The Lobster Pound is the class of the lobster roll.
We "had" a great one on the water here in Vermont. This year, portions are way smaller, price is higher.
Give me chips and slaw and I'm happy.
Truthfully, I think most people latch onto a place they like and it become fantastic. I only love the food, surroundings are secondary. Sorry, but TLP is the best on all counts.
