Probably authentic, as clients are from Mainland and servers speak broken English, but I think the food is just too heavy for me.
I got A2. Handmade Noodles "Spicy" in Soup w/ Beef, but this is not really soup you can drink. Unless you like drinking oil...tasty oil. There was a thick blanket of oil coating the noodles underneath. Noodles were a bit undercooked. The cow probably died of old age as it was tough and grisly.
I don't want to totally slam them 'cause it's probably authentic, just "off day"/not really my thing.
