I visited Emperor's Palace with my mom and dad last night, just a few days after their grand opening. Our first impressions were very positive and we're planning on visiting again soon to get to know their menu a little better. My dad was very impressed by their boiled chicken (see photo... as I'm not sure if that's an accurate English translation for this dish). The boiled chicken was very tender, but not bloody at all... which I'm told is something difficult to achieve for this dish. The ginger dipping sauce for the chicken was great. Our soup - mustard vegetable and pork - was fine and certainly as good as soup we've had at Siam Cafe nearby. The Chinese bok choy was also prepared very well.
If you decide to visit and are similarly impressed, spread the word - I'm not sure if these guys are marketing themselves aggressively enough.
