There are some lovely villages surrounding Melton with some decent places to walk, eat and drink. Personally recommend the Lakes in Eye Kettleby for a Sunday roast. 2 sides to the venue with the left side being dog friendly. Also if you like fishing i hear they have a few pay per day lakes.
The town itself is fine, but suffers like everywhere for decent shops, but decent enough for a stroll round and grab a coffee and watch the world go by
