Two Seattle girls will be visiting in the fall and are in need of some restaurant recommendations. We will only be in town for the weekend, unfortunately, but would like to have some great food experiences. I've just started to do some casual research but I would love input from some locals. We're staying at the Milner Hotel (78 Charles Street S), but are willing and able to travel as far as the public transportation (or cabs) can take us. The biggest limitation here is that one of us is a vegetarian, one an omnivore. Looking for breakfast/brunch, lunch, dinner and even happy hour. We are looking for one upscale dinner venue as well as several more casual options for the other meals. Thanks in advance, Boston chowhounders!
