oooh, fun, Maria, that's a great little area to shop...I used to work 1-1/2 blocks from there
back when I was a pastry assistant to swapper E. in SF at a fine dining restaurant in that neighborhood. Be sure to check out Market Hall. That's where I met Janet in NC for a coffee when she was here visiting. Market Hall has a bakery, coffee nook, deli section, absolutely amazing cheese selection and sections with purveyors of wine, fish, meats, fruits and veggies. I recommend parking in the back behind Market Hall (directly across the street from Rockridge Bart). It's a small free parking lot (just go around a couple times if it's busy as parking spots free up pretty rapidly). Street parking can be challenging to find so it's worth hanging out at that parking lot until someone leaves.
I've had banyuls vinegar before and it's lovely. Must check out that brand next time I'm down that way. Have fun on your shopping spree, Maria, that's a fun area to explore.
