Maybe not the best, but when I was there...
Annie's Cafe 4012 E. 8Th Ave. Chicken fried steak with biscuits and sausage gravy for breakfast with a spicy red beer to wash it down
On the main road from Denver to Red Rocks, just past it there is a small trout stream with plenty of visible fish in it, but I had a MH casting rod with an Abu bait caster and 30# braid.
Homemade salumi and cheesed at Luca D'Italia restaurant at 711 Grant Street, great meal. Actually the chef there, Mike, gave me my first fishing rod and reel as a going away present when we worked together in Boston.
My lady dragged me to the botanical gardens and it was actually really cool.
Have fun!
