The Tahoe Mountain Bike Festival would not exist without the mountain bike loving barkeeps at the Divided Sky, so definitely keep them in mind for late lunch, dinner, trail beta, and rehydration needs.
For starting the day, Freel Perk offers delicious espresso and food. Getaway Cafe and Meyers Downtown Cafe provide yummy traditional breakfast options.
Frescana Mexican Bistro is a great lunch and dinner option with a lovely outdoor seating area (useful if you are coming straight from the trails).
Holiday Market has groceries and a cool beer cave.
