I’m not familiar with Bar Sardine and don’t go to the West Village that much to eat, so my knowledge of eateries there is limited.
There were plenty of people at Chelsea Market last Friday night when I was there and on other days and nights I’ve been there, so I think it’s both a day and night place.
I think you should consider going to Otto, given what you’ve said about your ambitions (or lack thereof). It’s a little big to feel like a neighborhood place, but it actually is a neighborhood place, with excellent appetizers and pasta and a good, fair-priced wine selection.
In that neighborhood, you also might check out Old Tbilisi Garden, 174 Bleecker St. Strictly dinner except for weekends. I’ve never been there except for dinner, but the food is very good, though just a bit salty for me.
