Wow. This place really wow me.
There MUST be something wrong with this place during our visit.
We went in this tiny restaurant and stood for 5 minutes waiting to be seated. The staff clearly saw us (yes we even looked into each others eyes) but without actually (i.e. effectually) seeing us. They even walked by a few times right in front of us.
There was one empty table with a glass of water left by previous customers. Ok so we took it. Again the staff saw us walking in and the sitting down but no one acknowledged us.
So we waved down one server to take the glass and he did, politely.
Then no one ever came back with menu or tea or water or anything. A few minutes later we waved down the guy again to ask for menu. Then we waved him down to place our order.
We ordered dumplings and some other simple items. Waited for over 30 minutes and nothing came. Then we finally managed to wave down another server and he said something none of us understood (seemed not English or Mandarin or Cantonese). Then 15 minutes. Waved down again to ask for food and the server never got back to us. Then 10 minutes. We stood up and left.
Most surprisingly, on our way out, the staff again saw us without actually seeing us. No one ever stopped us. Wow.
