"Village atmosphere and good food"
Shifnal is a nice village about 5km from Telford. There isn't much reason to visit Shifnal except that is has some nice village shops and a good village atmosphere. If you don't have much time, avoid Shifnal and go to Shrewsbury or Ironbridge instead.
If you do want more information then use this website - it does list some of the attractions including the Monarch's Way,
Shifnal does has an extrodinary amount of places to eat and drink for a small village. If you are staying in Telford (say for business) and want to eat out, then go here!
All my Shifnal eating tips are now together on my Shropshire page.
