Sorry for the last-minute nature of the request: D.C. Hound here. I'm not infrequently in Cambridge, with time for only a single meal before a cab ride to the Airport -- as I will be this evening. If I don't catch a bite in Cambridge itself (Tamarind?), is there someplace that's a "must eat" between Cambridge and Logan at which a cab could drop me? Requirements: It must be a fairly quick meal -- on the order of 60-90 minutes, say. It has to be at a restaurant where I'll be able to quickly find another cab to the airport after dinner. And it should, of course, be delicious. Bonus points for something that's unique to Boston or that I could not otherwise get at the same level in D.C. Based on earlier raves here, I've had O Cantinho high on my "must try" list for some time. Is that a possibility (I've no idea where it is)? If so, is it still one of the best cheap eats in Boston?
Thanks in advance.
