I grew up in Troy and spent the better portion of my high school days working next door at Somerset Mall. Once I reached college age (and came home for christmas) I would go to McCormick's with my fellow co-workers. Since then, I've been back about a dozen times to visit old friends and co-workers. The bar is reguarly moderately busy (but not too busy) and full of local worker bees from the mall and the neighboring businesses. Happy hour is lots of fun at M&S with the $2 menu.
The restaurant is super classy, but I've only been to the restaurant once or twice. Usually, I go to M&S to get some fancy drinks, good hors d'oeuvres, and a relaxed and classy environment to meet with friends. There is a psuedo-dresscode, so don't go in wearing your KORN t-shirt or anything.
