Green tea in Japan is a different animal than the junk you find in the west. I expect that you might like houjicha (roasted green tea), especially a high quality one.
A company that makes really good black tea in Japan is Lupicia. You can find it in department stores.
I think there are a lot of second rate bakeries in Japan, although they might highly in a country like the US. I recommend Viron, which has a branch in the Marunouchi bldg near Tokyo station. Also they open at 9 am..... at least the Shibuya store. The problem is that many bakeries are in shopping malls or department stores that open at 10.
Artisanal bakeries open earlier. At least my favorite Levain, which is near Yoyogi koen.
p.s. Can't you say niku-wa in the sense of "regarding meat in general". Ga implies specificity. I realize that if you use arimasu then generally you should use ga.
p.p.s. I really don't like Mt. Thabor. Expats who live in Azabu-Juban rave about it for some odd reason. They can't even make a decent baguette and they make "old school" Japanese baked goods, which seem to be inspired by American Wonderbread ca. 1950s.
