After numerous meals at LSF Tysons, I gave up in December trying to convince myself it was worth the frustration. The room has all the appeal of an airport waiting room but the chowder and several grilled entrees were the basis of my self-delusion in returning. The wine list offers, as Rocks notes, a very nice selection at reasonable prices.
But the LSF Tysons service was so consistently inept and oblivious - wrong orders, missing items, ice tea glasses sitting empty for ten minutes despite repeated request - that I don't intend to return. That said, the Reagan Airport branch is a welcome relief. Yes, service is rushed but my experiences have been mostly positive as a beleagured passenger. I lived in Boston for three years in the late 90's and found the food quality and management of the Chesnut Hill LSF far above LSF Tysons.
I have also scratched Coastal Flats off my list. I have no problem with the Great Am Rest philosophy but the quality of the entrees became inversely related to the price escalation - more expensive mediocrity. Last time there, the daily special came out unrecognizeable. Halibut atop a slice of rye bread(!) submerged in a brown sugary sauce. Nothing like the description of a Mediterrean tapande. My companion's dish was also mediocre. Prior visits were equally unimpressive. Personally, I do not think CF is worth the wait.
BTW, Clyde's is running a halibut special this month. I thought the halibut was plated nicely and the quality quite good. As a pleasant suprise, the service at the Tysons branch was professional and friendly.
