The salads at Pluto's are the best deal ever. Their huge, and you can choose from huge variety of toppings and dressings, and add what you like. Add chicken for a bit more, or a slice of bread for only a quarter. They also have carved turkey, cooked veggies, mashed potatoes, fries, and sandwiches. I have no complaints on all of this, but I usually stick with my salad.
Casual place, where you go up and order what you want, pay, then take it to the table yourself.
