I went with a group of 7 others after work a couple of weeks ago. We had a similar experience as h&t - price range by the glass was $6-$9. Nice sized pours, nibbles were good, very accomodating staff - we had a really nice time and want to go back for a Tuesday chef's series tasting night.
I went last night and there were four offerings: two for $7, one for $9 and one for $10. They also had a selection of 5-8 hors d'oeuvres for $2-$5 and a cheese and salami plate for two which was $11 I believe. I only asked about the $7 ones which were an Italian nero d'avola and a 3 grape blend from the Languedoc, another red wine. I saw someone drinking a white wine as well. As far as I understand it, they change the lineup from week to week.
The staff was very friendly, they offered us a small taste of each of the two that we were interested in (mentioned above) and we got a fairly generous pour, ~6 oz. My friend and I both tried the nero d'avola which was nice but not something I personally would buy. It had strong notes of cinnamon and clove (as described by the shop person) which was too close to mulled wine for my taste. It was reasonably priced at $12 however. All in all, it was a nice little event and I will definitely be back since it is down the street from where I live.
