The United States is full of restaurants serving exemplary food. However, even if you're a regular at certain diners and restaurant chains, there are definitely hidden gems waiting to be discovered - some may not have branches in your state. 

Recently, Buzzfeed asked its community to tell them which chains should start expanding to the rest of the United States. Here are some of the most notable and mouthwatering ones:

Noodles and Company

This restaurant mainly serves different kinds of noodle dishes, notably pad thai. It's only available in 31 states and is based in Broomfield, Colorado. 

Pollo Tropical

It serves Carribean delicacies - it's best dishes include TropiChop, wafflie fries, and grilled chicken. So far, it's only available in Florida, Texas, Georgia, and Tennessee. 

Rita's Italian Ice

The Italians serve the best ice cream, considering it's where gelato (Italian word for ice cream) comes from. So far, it's only present in 25 states.

Burgerville arguably serves one of the best burgers around - one of best items on the menu is pepper bacon cheeseburger. Apart from which, it also serves fries, fish and chips, and milkshakes. Unfortunately, it's only available in Washington and Oregon.
