18. Del Taco’s Cheeseburgers
Yes, Del Taco sells cheeseburgers—and no, you shouldn’t be eating them. The patties are thin, overcooked, and oddly seasoned. They taste like an afterthought on a menu built for tacos. The buns are often dry or stale, and the cheese rarely melts properly. It’s clear the chain doesn’t put the same effort into its burgers as it does its Mexican-style offerings. Even the lettuce and tomato toppings can’t save this from tasting like a high school cafeteria lunch. If you walk into Del Taco craving a burger, it’s probably a sign you need to walk back out.
