As a gringo who has a interest in Latin foods and such, Compare Foods is like going into a museum for me. This is the newest Compare in Charlotte and worth visiting even if you don't like Latin foods. Why?
Becuase hands down, they have the best and cheapest produce section of any grocery store in Charlotte. They tend towards Latin flavors, but you will find three types of mangos (SPOILER-THEY COST .45 RATHER THAN $1 AT OTHER GROCERY STORES), plaintains are 3 for $1, there are five types of tomatoes, etc. Since I am eating more fruits and veggies these days, I take a trip to Compare to stock up on produce.
They have an excellent variety of meats (though I've never bought meat from this store). Even the frozen foods reflect Latin tastes; you will see more Goya brands than Stouffers. You will not find American staples, like skim milk or plain yogurt, stocked on a consistent basis. But if you're an adventurous American or Latin person seeking some traditional ingredients, this is your place.
