I absolutely love these patties, I can't be for certain but I don't think these have any preservatives, they taste fresh and are super simple to prepare, basically just stick it in the mini oven for 15 mins. These ones compared to Jamican patty from the grocery store is like night and day, no weird preservative taste, no freezer burn making the patty rock hard after heating and the beef tastes actually fresh.
These are awesome for a quick snack, you can get mild, spicy and veggie. I typically get spicy as it's not really 'that' spicy, just enough.
This location is kinda tough as parking is a nightmare but is in my general location so I put up with it.
Tip: Buy the pre-backed frozen packs, as it's easily reheated in the mini oven and comes out crisp. As well both locations are closed on Sunday.
