I'm a fan of burger Wednesdays although the service is always a bit sub par. I always find that I'm waiting in line longer than than the person(s) behind me, it's as if my food has gone missing in the lunch rush.
Otherwise, the burger with salad is always a great treat. Juicy, fall apart messy-ness, but really worth the mess. Be wary about the feature burger though, they always sound delicious and there are many different creative combinations, but they always seem to get a bit overzealous -- the flavours tend to get lost, maybe because it's so hard to keep the burger from falling apart so you can have a few decent bites in one shot. The salad is a delightful mixture of greens, spiced walnuts, dried cranberries and apricots...my only complaint is that the salad portion always seems so small.
