currently crushing on: mexico city

we're going on a field trip! mexico city has been on my personal (and professional) travel list for almost a year and a half and i figured it was time to make it happen before we hit the rainy summer season. i've been so inspired by all of the gorgeous, saturated colors and can't wait to check out a long list of restaurants, hotels and historic sites that i've been eyeing for quite some time. if we do everything on the list we may be eating five meals a day, which means i definitely  need to bring my most forgiving pants. 

i'm currently crushing on the mexican modern aesthetic, as well as the vibrant food scene. most particularly, i'm eager to just go and look at everything. as diana vreeland would say, the eye has to travel.

any mexico city recommendations? are the ruins worth the day trip?
