The Columbia Olive Garden always offers a large variety. The soup, salad, and breadsticks that come with the meal (with any entree you can choose salad or from a selection of soups, I reccomend the minestone) have free refills. There are many choices of main courses and the servings are so large I always take enough home for lunch the next day! The deserts are also wonderful and the prices are reasonable. The atmosphere is fun and the wait staff is most always fantasic.
PROS: Great prices, large quantity, fantastic food
CONS: noisy, sometimes there is a wait for a table
