Friends are visiting Bend and Sisters the weekend of Oct. 9-11. I find few posts on them.
Best guesses in Bend:
Ariana, Cork or Zyedeco (some like Blacksmith - looks pricey?).
Best guesses in Sisters:
Jens Garden (but small portions, and I can see limited selections and wonder overpriced?), Slicks for BBQ (I can't find it online), perhaps Martolli's for snack pizza, Sno-Cap or High Lakes for shakes and maybe burgers.
