I guess because you use the word 'town' that a shitty chain sub might actually be a true upgrade, but for anyone in even a smallish city, look around for little hole in the wall independent restaurants because I guarantee you can get much better food for much cheaper than the shit you'll get at chain restaurants. Off the top of my head I can think of at least 5 sub shops and delis in my area that will give you a much bigger better sandwich than subway, for a little over half the price. Then there's shawarma shops, Chinese take ours that will fill up the take out container so full that it's too much to eat in a sitting, burger places where you can sit down and have a burger and a beer for the price of a McDonald's meal and it'll be twice the size, pizza joints with walk in specials where you can get a small pizza for the price of a slice at pizza-pizza, Caribbean restaurants where there isn't even a fast food alternative, fucking lots of places. Don't settle for some bullshit just because it's familiar.
