Speaking of things that help immerse into an environment, I use EaterLA constantly. It’s a little difficult to see me here I’m so immersed in LA. There’s an Eater particular to LA, but there are also numerous Eaters specific to many individual areas as well as an umbrella, national publication.
I find the maps the most useful feature Eater provides. Two specifically, the Heat Map and Eater 38. Heat = Popular at the time (according to them), and 38 = a list of the best restaurants at the time (according to them). The maps show where each location exists within the city as a whole. Great for planning a trip around your usual town or your current town.
Sometimes Eater also publishes other relevant maps on a myriad of topics like, but not limited to, pizza slices, coffee, quick service, burgers… They’re incredibly useful and using them, like yesterday’s Eclectic 24, makes you seem cool. Just another way for you to squeeze into the cultural zeitgeist (At least you'll be able to squeeze into something after using Eater). So once you get hungry from all the head bobbing and toe-tapping you’ll know where to find the best food wherever you are (provided it’s a major metropolitan location that hosts a specific Eater website).
