Recently, this shop moved from a building in front of the station. They couldn't resist the vacant store where "Yakiniku Haraiichi." used to be. The shop is located next to the south of "Super Nishiyama" in Arakawa, across the road. There is a parking lot in front of the shop with space for about a dozen cars. Inside the shop, there are partitions that create a semi-private atmosphere. When I entered, there were no other guests. I informed the staff that I was dining alone, and they whispered something to each other. After their conversation, I was seated at a table closest to the kitchen. Looking at the lunch menu, they offered a wide range of options from yakiniku to hamburgers, bibimbap to meat suki, and yukkejang. When I asked about the amount of meat, they mentioned that yakiniku is served in 100g portions. Feeling like it wouldn't be enough, I ordered the 200g "Wagyu hamburger set". The demi-glace sauce that came with it looked quite rich. I tried a bite with plenty of sauce. It was sweet. Very sweet. I ate it while breaking the fried egg, but it was just too sweet for my taste. The hamburger itself, made with 100% Wagyu beef, wasn't bad. The three side dishes included kimchi with nagaimo, chilled tofu, and simmered beef tendon. They were all quite delicious, especially the simmered beef tendon which was tender and flavorful. It could even be a main dish. And then, the mysterious behavior of the staff... As I was using the restroom after finishing my meal, a staff member entered. Instead of using the restroom, they closed the door. What? Were they monitoring me? It made me feel uncomfortable... Well, never mind... Looking at the photos of the food, there was nothing particularly appealing... This strange and uncomfortable behavior made me feel uneasy as I left the restaurant. Note: The score is based solely on the taste of the food.
