Had Ramen for the first time last week. We were told upon sitting down that the Spicy Tan Tan and the Tonkotsu Black are the most popular. They're quite different from each other so it was tough choosing. The Spicy Tan Tan, as the name implies is a very spicy sesame flavour, with soft boiled egg, bamboo shoots, and ground pork. The Tonkotsu Black has a very strong garlic flavour with a soft boiled egg, bamboo shoots, and black fungus.
My boyfriend and I got both because we couldn't decide. We both liked the Spicy Tan Tan better and would recommend that one if you're having a hard time choosing. But it depends on your palette. If you're into spicy, go with the Spicy Tan Tan. If you're into anything garlic, try the Tonkotsu Black.
Both are super salty though. I would highly recommend asking them to use less salt. The flavours in both dishes are enough for a good meal! Will definitely be back to try some of the other dishes!
