Its awful, last time I went to eat out at a Subways I usually get the Footlong Flatbread with steak and cheese. A few years ago before the pandemic prices were fine and wouldn't mind getting 2 orders with whatever promotion sales they got going. But now I can't see myself paying over 15 dollars for a single fully loaded foot long sandwich.
Its not just Subways where prices are gone out of wack. Even Jack in the box, their Jumbo Jack burger is no longer that 2 dollar and fifty cent value menu item anymore and cost almost 5 bucks for the sandwich alone without a combo and 10 dollars as a combo. At least their tex mex tacos are still decently priced but everything there, specially their burgers is tiny compared to what you get at Carls Jr.
To avoid the urge to eat out at work lunch ours, I just bring a Hungryman TV dinner and stash it in the office kitchen fridge or bring my own pre-cooked and prepped food from home.
