Here are places that have closed this past year in Rockville Center--most of which I found closed after driving a half hour to eat there:
Neat little place with great breakfasts and tasty panini
Ate there a bunch of times--and a bunch of times more when I'd gone there but they opened (quite) late so I missed out. Last time... sign was done, place empty.
Filipino food on Long Island! How cool! But... 'tain't there anymore:
Just saw a Diners, Drive-Ins and Dives episode where he re-visits Brooklyn and goes to Brennan and Carr. Really wanted to try that dipped roast beef sandwich and hey! They have a Rockville Center location!
Since they have a working web site, the place obviously must be open... well, maybe not. No trace left. Drat.
