I, like most people, have Fri. off and want to hit one of those inaccessable places (for me in the Longwood Medical area with 30 min for lunch) that's only open on weekdays or only serves lunch specials M-F. Any suggestions besides Taiwan Cafe and Sam Lagrassa's? I probably will be downtown. Was thinking of Chile Duck on Boylston but am open to whatever's good and not available on Sat. or Sun. Thanks.
