My family and I were frequent Olive Garden customers until Macaroni Grill came to town many years ago. Unlike OG, I don't have to shout over the noise of other tables so my guests can hear me. I don't feel rushed by staff to leave my table once I'm finished with my meal. Meal prices might be a tad higher than OG, but the food is great and so is the service. The dining area also appears to be a lot cleaner than our local OG.
While I'm sure Macaroni Grill has its peak service times, I have never had to wait more than 15 minutes for a table and usually get seated right away. So, while others are waiting an hour in line at OG, I'm being served my entree.
