We have several here in Northern VA / DC / Maryland.
My two are very different. One (my normal shopping place) the guy wasn't very friendly to a noob, but has gotten better after shopping with him for three years. Good variety of grain, yeast and hops and good stack of equipment. Limited tastings and beer for sale. it is a little out of the way, so you have to go there with a purpose.
The other is a bit more hipster. It is in Arlington in a strip with several restaurants and bars. Focus is more on wine and beer tasting and sales. Good spread of grain and yeast, but not as high a turnover of grain, so not always as fresh. much smaller equipment offering as well.
Both did ok through the CV-19 by offering online ordering and pick up.
Still good to have a place to go and check out the equipment in person rather than ordering online.
