This is a chain restaurant with locations around Tokyo. I was meeting a friend from Saitama so meeting in Ikebukuro was the mid-point for the both of us. Onyasai does shabu shabu(hot pot) with a western flare. We ordered the tomato and soy milk broths. The menu said that the soy milk is popular with the female clientele-it was okay and found the tomato to be the winner. We opted for the ‘all you can eat’ and ‘all you can drink’ set. You get bang for your buck as you get a variety of vegetables and unlimited meet. With the 3400 yen set, you get both beef and pork; I loved the kalbi beef. The drink menu was extensive and well worth opting for the unlimited drink option. We also ordered, which was included in the set, mochi, cheese pieces, rice, avocado+potato salad, and tomato+pesto salad to name a few. Definitely check out one of their locations as the food is delicious. Good for: dinner, groups NB — Tabehoudai(all you can eat) & Nomihoudai(all you can drink)
