Awesome sauce and a meal for less than $10 are main selling points.
The bread's more like a baguette in texture compared to the fluffier white bread on a Subway or Quizznos. Some like the former, some like the latter. I prefer softer bread. Just know what you tend to like, nothing wrong either way.
Here's the clincher: They have delicious, juicy, thinly-sliced corned beef on rye; served hot. They have hotdogs too. For me at least, these two added options on the menu alone make this the winner in the battle of the franchise sub-shops.
They also have bottled specialty sodas. Although the place looks like they might sell weed too, they don't.
