Ahh Staveley is lovely. Definitely try the Watermill at Ings then.
Is it Ashes you are staying at (what I know it as locally, not sure what is officially called but it's on Ashes Lane)? If so it's slightly outside Staveley and you have a very busy dual carriage way to cross to get out anywhere. It's a nightmare and I've seen countless close calls over the years there from people pulling out into 60-70mph traffic.
Watch out for your sat nav trying to take you via Burneside as well (the village adjacent to Staveley), it's bridges are still out of action following Storm Desmond in 2015 and the roads are going to be closed for the next month or so while they do some work.
You are quite near Plumgarths where there is a farm shop/bakery and also a sourdough pizza place that deliver.
Wilfs and Hawkshead Brewery are right next to each other but check opening times as they both sometimes close earlier than you would expect in the evenings. The Eagle and Child in Staveley is OK and the newsagents/post office in Staveley 'the beehive' does great cakes, pies and sandwiches to take away.
There's a few nice walks around that area but a good one that will fill a day and is a bit more off the tourist trail is The Kentmere Horseshoe which can start in Staveley.
On the 13th September there is the Westmorland County Show nearby (massive one day agricultural show) and on the 14th September there is a torchlight procession and carnival through Kendal town centre in the evening. If that is when you are here be aware they close the main roads in Kendal from about 6pm onwards on the night. I.e don't try and book somewhere to eat in Kendal that night for 8pm and expect to be able to drive there.
