I live on that block in Carroll Gardens. Unfortunately, I don't think Dave's has survived, unless it's the place between the big hardware store and Victor's Dry Cleaners that has a brown storefront and no apparent name. It's a really random store. I've seen them put items for sale on the sidewalk--sometimes it's just one shoe with no match or a cooler. I've never been inside and I don't get the impression I'm welcome. Here's hoping it's not your beloved Dave's because that store sounds like it was awesome.
