This place has it figured out! As the name implies, each dish runs for $5, with options to upgrade to larger, more spectacular meals. They keep the portions small to make this possible, and by piling on their tasty matchstick fries.
That said, I mostly return so often because you can get good, but not excellent, food for cheap. Their sausage and mac & cheese is great, but slightly underseasoned and very tricky to eat. You might have the best luck ordering a few different things to share. They have tons of options, and they're very vegetarian-friendly.
