Milts is fun to stop at. My Mom lived about 3 blocks from there and I would walk my kids over to get ice cream when we would visit.
Fins is a fun trail to do for first timers there. Lots of slick rock to ride. Its amazing the traction you can get.
The Moab Brewery is a fun place and Eddie Mc Stiffs has decent pizza, I wouldn't say great but decent.
The Sunset Grill, (formerly the Mi Vida and prior to that was the private residence of Charlie Steen) is a fun place to eat and watch the sun drop over the mesa to the west.
Looks like so much fun.
