I used to come here a lot for their 8-bowl noodle and rice bowls--half rice bowl and half udon. Both sides were delicious but the portion was quite small in my opinion. Their beef udon is delicious and has a generous portion.
I came here again yesterday and ordered the beef nabe (Hotpot). There was udon and rice and an extra egg on the side. The broth was SUPER sweet and salty and so were the udon, the veggies, and the beef.
When I got the bill, I was informed that they added a 12% tip to it already. I was quite confused since I went alone and there was no sign or note that said tips would be added automatically. The service was great (I was the only one at the store) so I was going to tip them 15%, but adding tips to the bill was quite odd to me.
tl;dr good rice and udon, Hotpot broth too sweet and salty, they will add a 12% tip to your bill by default.
