I love the name.
E Mama E Rou has terrific goosemeat - succulent and fresh, lilting and savory.
You can locate it at Jingmei Night Market - take Jingmei MRT Exit 1 and when you exit, turn away from Roosevelt Road, instead heading left along the lane that takes you to the night market. Across from Cafe 85 is another lane that bisects Jingmei Street (the night market main drag) which is laden with good options. The "stuff on sticks" guy to the right is also quite good.
Anyway, walk in a bit, and it's right near the little shrine on the left. It's a basic Taiwanese 'joint' - not a restaurant, not an eatery, not a cafe, but a joint - where you get goosemeat, white or dark. it comes with bones and skin, sliced onto a plate with two dipping sauces the way cold chicken does (but the sauces are different). You can order noodles to go with it, made with a velvety goose broth, as well as xiao chi and seasonal vegetables.
It's really, really good. They do an excellent job with high-quality meat, the way any little joint should.
Sorry that I'm lazy about typing in Chinese; I would really prefer Pinyin input - sorry, I know, evil Communist Pinyin - and it takes too long to do the bopomofo. I am practicing though. I'm trying to do more reviews of Taiwanese restaurants as opposed to foreign food. It is easy to get reviews of foreign food in Taipei online (I subscribe to Hungry Girl, so I know) but really hard to get info on the little places - the joints - that serve the best local food and snacks.
Someday I'll write an epic post on the myriad kinds of onion pancake and where to get the best ones, I swear.
