We were tempted by the restaurant when we went by on Mother's Day but it was overflowing with a long line for the occasion. Did note it for future reference and it was no problem to get a table on a normal weekday evening.
Missed out on katsu while we were in Japan, but to be honest we can do frying in Taiwan just as good anyway. The restaurant in the XinYi Mitsukoshi A9 building is important from Japan, complete with the the bowl of toasted sesame seeds which you grind up yourself and mix with their special BBQ sauce. The different pork cuts are moist and not too oily after the breading-and-frying. The katsu-asparagus roll was good, too. I think I prefer tempura-fried shrimp over the katsu-shop version, though.
The unlimited shredded cabbage is standard issue for a katsu shop but they also had a nice light dressing which gave it a bit more flavor than usual. Found the egg a bit overcooked in the SIL's egg+katsu combo. I think it would work better being runny like in an oyakodon.
About 350NTD per head after service charge isn't super-cheap, but it's not bad for a nicely decorated space in a fancy department store. A good mid-range option to keep in mind as they expand with more branches in Taipei.
