I don't eat out very often so I can't be much help on restaurants.
Kinda depends on what kind of stuff you like to do. Lot's of outdoor activities
Rocky Mountain National Park is about an hour West of Loveland. If you have the time, it's awfully pretty.
Some decent fishing if you like it. The Big Thompson runs through Loveland.
I don't think they're running rafting trips on the rivers this late in the season, but it's a possibility since we've had pretty good rain this summer. Fort Collins is 15-20 min north. The Poudre River runs through it. Fort Collins has a number of small breweries, as well as a Budweiser plant that gives tours & tastings.
Old Town Fort Collins can be interesting, though a bit crowded, I think the kids are back at CSU.
If schedules can work out, I'll buy lunch!
