Haven't seen this one before, Motoazabu Hills Forest Tower.
We went to a new neighbourhood today, Azabu-juban, which is a lot of fun to say. (It's Golden Week in Japan, hence the various outings.) Our main goals were a burrito place, which aren't that common in Japan, and a temple that is known for having several cats on the grounds.
It also turns out that Azabu-juban is full of embassies and very expensive real estate.
The burritos were a win, a bit pricey, but tasty and a good size.
I think this is the first time we've had burritos in Japan in the almost 5 years we've lived here?
Now that we know this place is good, there are a couple of other locations we can try which might be a bit more convenient to get to.
The temple was nice, but the cats weren't very interested in interacting 
As just a couple more tourists encroaching on their leisure time, I can't really blame them 
@brook Hmmm. Good to know you aren't in a burritoless wasteland.
It's wise to be leery about Mexican food in places that far afield. I was warned off trying any of it in Australia by an Australian who knew the difference and told me that he'd only found one good Mexican place in the whole country.
I used to be leery of Mexican food when I crossed the border to my north as well, but the advent of smartphones has made it easier to find good places.
