Providing further evidence of the eastward creep of the SGV food locus, 3 new Taiwanese restaurants have opened up in Arcadia, including one at a site not previously a Chinese restaurant. Perhaps of greatest interest is Taipei Garden, which replaces the veggie restaurant at Las Tunas and Baldwin, which raytamsgv indicates is relocating to Rosemead, perhaps under the name Lunar Feast (signage there is conflicting). Taipei Garden seems to be an affiliate of, but not a branch of Liang's Village. Everything indicates that Taipei Garden is the name of the restaurant, but there is also the Mama Liang logo on the restaurant exterior. However there do not appear to be any other references to Liang's in the restaurant. In any event they're doing a booming business.
Further up at 1220 S. Baldwin is Shawn Cafe, which is the successor to the successor to Machi Fusion. The previous restaurant was there for such a short period of time that I completely missed it. Finally in the shopping center at 713 W. Duarte Road is Carol's Cafe. I'm not sure what it replaces, but it wasn't a Chinese restaurant.
Note that all three of these restaurants opened up in December, so they belong on the 2012 list. Still looking for the first 2013 opening.
