I didn't understand what was all the fuss about Taiwan Cafe, until I tried it myself today for lunch. I must admit I am now a believer. The place was completely packed for lunch; I had to share a table with other couples and single diners. Ordered only dishes "not for the faint of hearted:" fried pig's intestines, chilled pig's ear, blood pudding rice cakes, and soup with tripe and blood pudding. Unfortunately, they were out of duck tongues ;). The fried pig's intestines were just incredible: topped with thin strips of fresh ginger, the texture and the taste of the intestines were surprisingly similar to Peking duck. The blood pudding rice cakes were in the shape of 1 inch squares, served in a soy based sauce, and topped with sugar. Couldn't get my hands off of this one! The pig's ear was very similar to a Polish cold cut called salceson. I liked the tripe and blood pudding soup very much but it wasn't as tasty as the appetizers.
Overall, this place is just fantastic. It is probably the most interesting and adventurous dinning experience in the Boston area! Thank you guys for bringing it to my attention.
