Usually I'm not a fan of chain restaurants, but you can't help but to love the Macaroni Grill. The servings are insane (I usually get the build-a-pasta dish) and the wine prices aren't terrible. This is my favorite of the Metro Detroit Macaroni Grill's because of it's quick location off of I-275 and it's large size and not-too-bad faux italian decor.
The service here is usually hit-or-miss - sometimes you get very friendly waitstaff and sometimes they are grumpy. Frankly, you don't come here for the waitstaff. You come here for the enormous servings of delicious delicious pasta (also I've heard the Chicken Parmesan is yummy too).
The place is usually packed at lunchtime with traffic from the surrounding office buildings and during dinner hours with the yuppies from Northville. I suggest you go here on a Sunday or take a late lunch.
