Food Recs in Mendoza, Ushuaia, El Calafate and Buenos Aires

[Losmith]

Hello fellow chowhounds!

My husband and I are going to Mendoza, Ushuaia, El Calafate and BA for a couple of weeks, and would love some recommendations on where to eat. We were in El C and BsAs three years ago, but this is our first time to Mendoza and Ushuaia, and we would like to make the most of our meals in each place. Also, while we know the beef is phenomenal, it would be great to have some suggestions that aren't simply steakhouses/asadors. We'll be spending Thanksgiving in Mendoza, so any special recommendations for that meal would be really helpful too!

Thanks very much for any guidance you can provide!
