My partner and I just moved here from Oakland, and we have been keeping an eye out for good barbecue. Thought I'd report on two really great options we've found, even though they're not exactly centrally located:
1) Bailey Barbecue, Julian
We shared a full rack of ribs for lunch (along with the two sides we chose -- cole slaw and onion rings) and didn't need to eat for the rest of the day. The ribs were the perfect texture -- cooked to a toothsome tenderness. We loved the sauce; it was sweet, tangy, and had just the right spiciness. And the service was fast and friendly. $29 for the full rack and two sides; I think the half rack was around $18.
2) Jo's Texas Brisket at Chula Vista Farmer's Market (Thursdays, 3-6pm)
Neither James nor I have had much luck getting brisket that isn't dried out, so we don't usually order it. However, they gave us a sample, and it was so juicy and perfect that we got a sandwich. Juicy brisked piled high on a plain hamburger bun, with or without sauce (James chose light sauce). Delightful. $7. http://josbrisket.homestead.com/
