Some restaurants have a signature dish, that one menu item that everyone agrees is spectacular. The same is true of sandwich shops. Although the bar is set high for sandwiches here in Boston, there are a few stand outs that continue to attract loyal legions of fans. If you're seeking an unforgettable sandwich experience, then you have to try these 10 iconic Boston sandwiches:

1. The Fancy (Mike and Patty’s)

When a breakfast sandwich is done well, it can be a thing of perfection. That’s the case with The Fancy at Mike and Patty’s, in which egg and bacon are paired with cheddar, avocado, red onions, and the all-important mayo sauce. Don't you just want to take a bite? This restaurant is located at 12 Church Street in Boston.

2. The Porchetta (Pennypacker’s Fine Foods)

Pennypacker’s is both a restaurant and a food truck; you can savor the restaurant’s signature Porchetta sandwich at both. It features Italian, skin-on roasted pork that has been seasoned, cured, and marinated. The result is a tender, savory sandwich that has earned Pennypacker’s quite a number of devoted customers. The brick and mortar restaurant is located at 514C Medford Street at Magoun Square in Somerville.

3. Snappy’s Famous Pork Chop Sandwich (State Park)

The star of the dinner menu at State Park is Snappy’s Famous Pork Chop Sandwich, a behemoth that unites juicy pork with beef chili and coleslaw. If you have the appetite of three NFL-players, this will certainly fill you up! State Park is located on the lower level at 1 Kendall Square, Building 300, in Cambridge.

4. The Pilgrim (Mike’s City Diner)

This South End diner is home to The Pilgrim, a sandwich impressive enough to have been featured on Food Network. This Thanksgiving-themed dish combines turkey, stuffing, and cranberry sauce into scrumptious sandwich form. Mike’s City Diner is located at 1714 Washington Street in Boston.

5. The Roast Beef (Roast Beast)

The sandwiches here are customizable, but the key is to combine roast beef with the restaurant’s signature "Thermonuclear Sauce" and add your desired toppings and cheeses. The sauce provides a burn that comes on slowly before building into the kind of scorching experience you expect from ghost peppers. Roast Beast is located at 1080 Commonwealth Avenue in Boston.

6. Fried Chicken Sandwiches or The Roast Beef 1000 (Cutty’s)

Frankly, it’s a tie between the epic Fried Chicken Sandwiches – available just once a month at this Brookline eatery – and the Roast Beef 1000. The latter includes slow-roasted beef and sharp cheddar, topped with crispy shallots all married together with 1000 Island dressing. You’ll find Cutty’s at 284 Washington Street in Brookline.

7. Atomic Meatloaf Meltdown (All Star Sandwich Bar)

This isn’t your grandma’s meatloaf. The Atomic Meatloaf Meltdown brings the heat, with a habanero hot sauce balanced with a hint of sweetness from red onion jam. The grilled meatloaf has a crispy exterior and juicy interior, and all of these elements come together to create a memorable sandwich. All Star Sandwich Bar is located at 1245 Cambridge Street in Cambridge.

8. Famous Rumanian Pastrami (Sam LaGrassa)

This Boston institution has been going strong since 1968 and is best known for the Famous Rumanian Pastrami. Fair warning: this sandwich of dry-cured, smoked beef on light rye will make all other pastramis seem like pale imitations. You’ll find Sam’s at 44 Province Street in Boston.

9. Corned Beef (Michael’s Deli)

The award-winning corned beef at Michael’s is a succulent delight that elevates any sandwich. The meat is pickled in the Bronx and then cooked in Brookline each day. Try it in the Corned Beef Reuben or Rachel. This particular sandwich has been wowing foodies for 40 years! Michael’s is located at 256 Harvard Street in Brookline.

10. Fried Fluffernutter (Biltmore Bar and Grill)

Who says that sandwiches have to be savory? If you’re a fan of the humble Fluffernutter, you’ll want to check out this decadent dessert sandwich that’s filled with gooey goodness. The Biltmore Bar and Grill is located at 1205 Chestnut Street in Newton.
