OK then - when you get to the ring road turn right (probably signposted to Horsforth, Bradford...)
Then straight across next roundabout & straight at traffic lights (Sainsburys & Homebase on your right at these lights).
Then straight at next lights. Then get to a big roundabout - turn left (signed A660 to Headingley, city centre).
Keep on going for a couple of miles down here, through far Headingley. You'll get to some traffic lights where there's a row of shops & restaurants on your right (Salvo's & Dynasty are the restaurants. Turn left here, down Grove Lane. after 20 yards the round bends round to the right, but there is alaso another road which goes straight on. Go down here - this is Shaw Lane(effectively turning left off the main road). Sala Thai is jsut along here on the left - it's a big old house, & there is a sign for it at the entrance.
I hope this makes sense! If not - let me know & I'll try to make it clearer
