My experience at the restaurant in chronological order:
1) Walk into the restaurant and was asked to sit at a table
2) Ordered and got up to get tea.
3) Walked back to my table and my order was there. (Literally 30 seconds after I ordered)
4) Finished eating in 5 minutes, paid, and walked out.
Word of Warning: The XO chili sauce is VERY hot so don't add too much or your mouth will literally be on fire.
This place is even faster than a fast food chain. I was impressed with the speed and the noodles were on par with the soup. Never disappoints.
