Man, Big Mouth's is a great place for a quick hotdog/burger lunch! The decor of the place is okay and they have wooden park benches which is a nice break from the standard setup of most places on Green St. I got the char polish sausage with the sports peppers (they were nice and hot), onions, and mustard. Very tasty and a decent size for about $5.50. The fries were quite good. Freshly cut and seasoned. They are like Murphy's fries but bigger and better so it's another leg up for Big Mouths.
A couple of other comments: This is slightly farther than the rival Hot Dog Stand but I think the quality of food is better and maybe a higher price. I wish the decor was a little better but the price and food makes up for it. One peeve is that they use Styrofoam cups for drinks which is something I wish they would fix. This place really deserves a 3.5 but I will give it a 4 because I enjoy it a lot.
