My parents introduced me to Bluegrass a while back, and I am grateful to have found this quiet lunch spot with great food and solid beer offerings.
They have six beers on tap, normally Midwestern offerings that will be enjoyable for craft beer aficionados and newcomers alike. Their bottle list really gets into the nitty gritty micro stuff, though, which is a fun change. My impression was that their menu emphasized wheat beers, but they have about 30 bottles at any given time, quite a few of which are lesser known beers from regional breweries.
There is a small bar area, but usually I am here sitting in the restaurant area, and the service is spot on. The wait staff will not hound you, but they will notice when your drink is running low and offer you another.
The food is always delicious. They focus on Cajun style cooking, and each dish I have had has been delicious. The key factor underlying their success is dedication to quality ingredients. Using great seafood to start almost ensures the result will be delicious.
The food prices are not cheap, but you are paying for quality food. The beer list is very inexpensive for the Chicago area, and they have 20 oz. pours for some drafts.
