Quote ="ex Bull Dog"There's one in the Northern quarter (name escapes) that is supposed to be excellent'"
You are propably thinking of one of the 'rice and three' curry cafes. Most likely This and That or Yadger cafe. Both of which are excellent.
The rice and three cafes are unique to Manchester. Simple places, originally set up to feed the India workers in the Manchester mills. Think Karachi but more canteen style and only open during the day.
Have a read here if you are a curry enthusiast:
