Thanks to JB's rec., I finally stopped by Andrea's in Putterham Circle in Brookline for some whole pickles. They are half-sours, 3 HUGE pickles for 4 dollars, and they are super crisp and fresh. I asked where they get the pickles, and he told me they are Regal Crown brand pickles....I googled them (Regal Crown Foods), they're made in Worcester. I wonder where else they are sold around Boston?
Anyway, thanks again JB for the recommendation!
