There is a Yak & Yeti Local Foods Cafes, QS kiosk right outside the Yak & Yeti TS restaurant. Difference is bigger menu and sit-down, served meal at the TS. Less options and take-away at the QS.
Big difference. TS has a much more extensive menu, and your are in a highly themed, air conditioned dining room being served by waiters. We thoroughly enjoy the experience and food and I recommend it.
