It used to be that Drew's had great Yelp reviews. An interesting trend I've noticed with Groupon is that, at least in Chicago, it's a great way to kill your Yelp rating. The sudden surge in business tends to be much more than the business is really prepared to handle, and everything naturally suffers when that happens. Particularly in Groupon's hometown, where their high market penetration means they act as the engine behind a veritable tsunami of deal chasers that roves around the city, randomly swamping unsuspecting mom-and-pops and neighborhood holes-in-the-wall. I used to be a regular customer at Drew's. But I have a habit of ceasing to go to restaurants for a month or two when I hear they did a Groupon. (Not out of protest or anything. It's just that flooding a place with Grouponers tends to make it a less pleasant place to eat.) I'm definitely not the only person I knew with that habit.
