colleague of mine is looking for a place to take his family for dinner on saturday to celebrate his 12 yr old daughter's birthday. birthday girl wants to go out for sushi to somewhere that has the low tables with pillows to sit on. (shame on me for not knowing what this is called.) family lives in sudbury but is willing to travel as far as brookline and even boston. does anyone know which notable sushi restaurants offer this kind of seating? yama in wellesley is already booked up for those tables. thanks!
