Finally gave this JP spot a whirl. The good: serious cocktail craft, cool atmosphere, good music on the sound system, very good food at very fair prices. Best dishes were hot wings (not something I usually order outside of Buff's, but they looked good in the bar), a chicken and spinach soup, shepherd's pie, half a roasted chicken, grilled salmon. Was less impressed by the flatbread pizza (a little dull) and the pasta Bolognese (ditto). Reasonably priced, modest wines, lots of options for vegetarians.
The only off notes were service related. Owner and hostess were really on top of their game and pitching in on dining room service, but our server was of the "well-meaning but ineffectual" school, making several screw-ups and not really appearing to pay more attention after the first one. Annoying, but not enough to prevent us from coming back. Next time I may dine in the bar, though, to avoid huge delays before and between courses because our server couldn't seem to listen carefully (repeatedly).
