We will be in Boston this coming weekend and need a recommendation for Sunday evening. We're looking for very good food and a pleasant ambience at mid to upper mid-level prices. We don't want to break the bank but we are also not afraid to spend a little money. We're having Italian on Saturday, so prefer not to go that way (unless you have a stellar recommendation). Anything other than Asian would be fine. I've done a lot of searching on this board for a week or so, but I've not really been able to come up with any outstanding recent recommendations. Thanks.
