Yes, it's still there.
1. Go to the
Metromix home page.
2. Click on Restaurants, just below the Metromix logo.
3. On the right of the page, you'll see a Calendar of Events. Click on the date you're interested in.
4. It will then only show a few specials, but below those few, you can click where it says Show All xxxday's Restaurant Events, and you'll see lots of them, with many pages for that particular date.
This method only works for dates in the upcoming two weeks. But the web page that results at the end of it, showing all the events for a particular day, also shows a calendar on the left, in which you can then click on dates as far out as you like.
