Where can you eat if all the seats are taken?

If it's a nice day and you have a car, you could take your food up the hill to Green Hill Park, up Belmont St to Bell Pond, or a little farther on the same street but opposite direction, to Elm Park on Highland St.. There's not really anything else nearby.

Your vehicle, with the heat on. With the eat.

Worth sitting on the side walk to eat

Somewhere else.
