Sorry for taking so long to answer! Where i live, only treats like alfajores (a kind of sweet cookie sandwich) or other chocolate stuffs are aimed at adults, and mostly there arent many processed monstrocities (except when buying street food because boy. Ohhhh boy.) I'm actually argentinian!! Colombia is GORGEOUS and its vibe is kinda like Ecuador's, but going there is totally worth it!  The thing with Argentina is that it's just. HUGE. I mean, you have absolutely every climate and every terrain, but you're gonna have to travel quite a while or plan visiting only one or two places in different points of the country so that's a heads up! From my personal experience: if you like the city, by all means, stay in Buenos Aires. It's gorgeous, it has everything from the usual tourist things (La Boca, the MALBA museum, etc) to a nice architecture and history (and the nightlife is pretty good). Plus, if you want, it has some hiking places between 1-3 hours away from the city like Tandil or San Pedro. If you prefer more adventure and like camping or hiking, Mendoza (the Cañón del Atuel specially), Córdoba (not the capital tho, try General Belgrano and other areas like La Cumbrecita) and Neuquén are specially nice in summer! Lots of lakes, rivers and mountains (plus Mendoza is the biggest producer of argentinian wine, you can visit the wineries and get guided tours). These places were also where most german and swede immigrants went so there's quite a cultural impression, specially in food and architecture. OH and the 40 route!!!! Literally the go-to road for sightseeing. Unless you want to get to Tierra del Fuego and the end of the world, going to the south beyond Santa Cruz is mostly for skiing. Then you have the north of the country, which is SUPER close to Bolivia both geographically and culturally, and then the northeast of the country which mostly has historic value (it isnt.... amazing tbqh) until you get to Misiones, which has the Cataratas del Iguazú! Piece of advice tho: absolutely ignore the beach. If by some ungodly reason you end up in Mar del Plata or Villa Gesell, I'm not gonna lie, they're super fun cities, but the argentinian coast is trash :( ALSO always asume every price tag is in pesos, not US dollars. Fancy restaurants try to scam people with this. ((Christ sorry i get super excited talking about the Best places for vacations)) ((Also if you end up coming, try as many different brands of alfajores as you can, specially cachafaz, capitán del espacio, terrabusi and águila... If you have a sweet tooth you wont be dissapointed)
