Just a quick beep to try to help this subject come up in the Google search: We went to Cracovia in New Britain this past Saturday for dinner, and loved it. Except for an awkward period at the beginning when we felt like we were being intentionally ignored by the waitstaff (as in, we weren't even seated), we were treated just fine. The plate o' pierogis that the SO ordered was superb, as was the bigos that I ate. Got a good Polish beer (Helvetius, IIRC) to go with, and it accompanied things just fine.
Down sides: The mashed potatoes that came with my bigos were mediocre, and the bigos could have stood to have more pieces of meat and kielbasa.
General notes: Cracovia closes early -- 8pm! -- so I'd recommend going by 6.30 or so. We arrived near 7.30, which may account for the cool welcome.
