I've eaten here several times over the years, and am happy to report (based on my most recent visit after a lengthy absence) that the quality of the food and service has maintained consistency.
I wasn't feelin' the fish during my recent visit, so I selected the walnut and greens salad followed by the roast chicken. The salad hit the spot, with lots of blue cheese, candied walnuts and spring greens. The bread brought to the table was warm and delicious. The half roasted chicken was presented on a bed of mashed potatoes and spring vegetables (yellow squash and zucchini) and was perfectly cooked. The potatoes sopped up all of the meaty juices from the chicken, which made them extra delicious.
When I visited, the bar area was hopping, so those happy hour specials that people keep mentioning in other reviews are probably worth checking out. However, my sole goal was to eat, not drink.
I've found M&S to be one of those chains that you can pretty much rely on no matter what city you're in, especially if you're a seafood lover.
