I go there a couple times a month and never had a meal that didn't delight the tastebuds. The food is still putrid, coffee criminal. They do pitchers. Brewpub serving all Sam Adams . Click Here to see the BBC page entry for this bar.
Nachos are good, food mediocre.
Beers vary widely - obscure ones occasionally quite stale. They make some nice brews and give short tours. They brew up several terrific recipes. Underground brews custom label beers for a number of local establishments. In addition, there are some VERY well-known pubs interested in having the Underground do a custom recipe and label for them.
