Coming from one of the highest immigration areas in the US, it is hard to find many places in the world where you can have the sheer variety of authentic mix of foods as you find here. The foods I miss most though when not home are the ones they make terribly wrong in other regions, such as good Mexican food, Barbecue, Hong Kong Chinese food, Steaks, Cajun food and Southern favorites like Fried Chicken and Chicken Fried Steak. The Northern food that dared called itself these things were horribly bland and pretty gross by comparison. These foods are supposed to be spicy, smokey, non processed and made with fresh quality ingredients, the stuff they sell elsewhere are no where near what it is supposed to be. If it isn't spicy and fresh, they are not making it right. You do not make these things from a can or frozen crap. YUCK.
EDIT: One of the worst offenders is TACOS. Beef Tacos should be made with flank steak (not " ground beef" that is so gross) If it doesn't have red wine vinegar, Orange, Cumin, Cilantro, Chili powder, Fresh garlic, cloves, and a Mexican Tequila such as El Jimador 100% Agave or Tapatío, IDK what it is but it isn't tacos as far as I am concerned. XD
People using quervo and think they know what they are doing..YIKES! lol
