Gwennies, one of my favorite restaurants in Anchorage, is a short drive away from the Hilton Garden Inn. I prefer the town when it is a little warmer...there is a spectacular jogging trail along the water starting in downtown Anchorage and continuing towards the airport. I'd echo the previous folks who encouraged you to check out the Seward Highway. If you make it to Kenai, I'd encourage you to stop at Suzie's Diner...they have the best tasting water I have ever experienced.
