Yeah, I stopped at it a few weeks ago...the biggest thing missing in order to add it is which business tag to use.

It seems too small for shop=supermarket, and I'm not sure how well shop=convenience matches given that this place struck me as much more specialized. I think I saw baked goods and prices for coffee as well iirc?

Basically, if you can use that experience to find a good existing tag for the business, please add it. There's a list of the most common shop tags and descriptions over here: https://wiki.openstreetmap.org/wiki/Key:shop

I did some digging as well, my best guess is the sorta uncommon shop=grocery (https://wiki.openstreetmap.org/wiki/Tag:shop%3Dgrocery) Not well enough acquainted with the store to say for sure though. Suggestions are appreciated!
