So I stopped last night, as promised, to pick up dinner.
It is definitely in the Binny's lot and still has the Jin Mandarin sign up. The only tipoff that it was indeed Katy's was the enlarged newspaper article in the window. The new location is enormous compared to the Westmont spot with several tables. It was obviously a work in progress with a ladder in the corner by the wall mounted flat-screen TV. It is not an open kitchen so I could not see who was back there. I put my order in and the man asked if I had been to the other location.
When I replied that I had, he smiled and pointed to a gentleman and confirmed that he was the owner of both locations.
I have not been to the Westmont outpost in a couple of months and cannot attest to having seen the new menu. But I can tell you that the new menu here is huge. It had well over 200 items listed. While it still had the noodle dishes I love, it also had many of the usual Chinese options such as kung pao chicken, etc. But it also included many unusual items I have either rarely or never seen offered.
Now for the skinny: the schezuan beef noodle soup I had was delicious and just about as good as I remember. The stir fried noodles and chicken was also up to the task. The onion pancakes with pork (one of my favorite dishes at Katy's) was fair but disappointing. It was dry and lacked the usual depth of flavor.
Being that it was their first night, I will forgive the pancake dish and consider it a very positive start.
