I order from Talloverde every 10 days or so.
And Casa China in Chinatown on Arribenos (sorry new keyboard haven't figured out the accent for the n yet) and Juramento (mid block by the dragon arch). Has a huge variety of rices, beans, dried mushrooms/chilis, spices, and soy products I haven't seen elsewhere (milk, tofu, cheese, mayo, dried tofu), and seitan. They have vitamins and many other stuff. I pretty much use that as my main grocery store since I eat vegetarian at home. I been drinking guava juice a lot lately, and I never seen that anywhere else.
