What is it like to live in Miami?
As someone born and raised in Miami, I have much to say based on my own experience on this topic. I'll try to cover the things helpful to someone comparing things to any other city; the entertainment culture, weather, public transportation and also culture in terms of people.
So many people refer to Miami as culturally diverse, though it’s far less “a little bit of everything” and more so very diverse in Latin/Hispanic Spanish-speaking culture; Cubans, Puerto Ricans, Dominicans, Colombians, Venezuelans, Chileans, etc. This high concentration definitely makes it unique. There is an established Jewish community in South Florida - and also pockets with Haitian residents, though I didn’t have much exposure to either in the area where I grew up.
People think of Miami as a nice and warm place to live, but I'm not sure if they realize it's very humid and often sweltering hot to the point of discomfort. If you don't mind frequent heat, moist air and no change of seasons, it could be your dream. :)
To no surprise, it is hands-down, the best place in the country to find authentic Cuban food. If you’re not familiar, look up things like Ropa Vieja, Mariquitas, Congri and Platanos Maduros to name a few. My mouth waters just thinking about it. :) Hialeah is a part of Greater Miami area in Dade County and you will find plenty of really legit and affordable Cuban food there in particular.
In terms of general vibe, people are unfortunately known for being less friendly and sometimes outright rude. It's much less common for people to hold a door open for you, for example. In some cities, people might greet you in an elevator or even make polite conversation while waiting in a line; much much less common in Miami. (There are, of course, exceptions to the rule and some more friendly and polite people here and there. And of course, no city exists without some rude people, but it’s just more common there.)
