Hi Kathy, I know lots about it! I live about 10 minutes away and we go for coffee there all the time.
It's a Shell Info Centre. It has a Tim Hortons and Wendy's, a small arcade and a Nicholby's store (lots of free Ontario Travel brouchures)on the first floor. The second floor is basically a large sitting area. There is an office upstairs, but no one uses it on weekends. There are washrooms too. The tables/chairs are those standard four chairs attached to the tables. They are fairly close together but they are permenantly attached to the floor and can't be pushed together. There are two sections with bench seating, they aren't near each other. One bench seating area holds about 12 to 16 people. The place is showing it's age, no frills type of room, and it's definately not the Rain Forest Cafe. But it is inexpensive and holds lots of people. Very easy to access from eastbound 401, it's just metres past the Winston Churchill exit. West bound 401 (Toronto) folks will have to exit Winston Churchill (exit 333 westbound 401) drive on the overpass and back onto the 401 eastbound.
Hope this info helps. My family likes having Timmy's for lunch there because it's usually dead and my kids can run around while I enjoy a coffee. S
