This is sad to read. I've enjoyed the food there on several occasions. My wife and I ate there with our infant son in tow. I actually think that on the early side of dinner, the bar is an ideal spot to take a kid. I've also stopped in to pick up food to take home. But I have to agree with much of what has been said here. Unless you keep tabs on this site, or read a handful of food sites, there is no way to know that the place exists. Alchemy should do more neighborhood outreach/marketing, like hand out flyers at the Greenmarket that play up the connection to John Brown Smokehouse.
The idea about including a couple fixed-price sandwiches on the menu is very smart.
And they do need to be consistent. The first time I tried to eat there, they were out of everything we really wanted to try, so we got nothing. If I showed up and the place was closed, I wouldn't go out of my way to return.
It's only been a few months and no business can really establish itself in such a short amount of time. If they aren't able to stick it out for at least a year, that's bad planning on their part. Which is a shame, because the BBQ is excellent and a great addition to the neighborhood.
