Tantan Noodles Kitchen Lotte Mall West Lake Hanoi is a tantan noodle shop on the third floor of the food hall at Lotte Mall West Lake Hanoi. It serves tantan noodles and cold tantan noodles, with a thick peanut and bean-based broth, along with cheese tantan noodles and sets that include soy sauce egg rice and chicken rice. On weekends and at lunchtime, the shared food hall seating fills up quickly, so you need to take a seat first. Food takes a long time to come out.
