I recently posted a question about Tallgrass in Lockport, since we were planning to go for our anniversary. One of the respondents asked me to post my opinions after we went. Tallgrass is a wonderful restaurant and a great value for your $$. The only downside is the location - a bit out of the way. If that restaurant were in Chicago, it would be much more crowded and the prices would be much higher. I would recommend it to anyone willing to make the trek.
