I've just begun to start a google spreadsheet with restaurant wine markup calculations. So far a friend and I have done pinot noirs at Rivoli and Bay Wolf. Both these places are marking up by less than 100% (based on average prices from wine searcher), often substantially so, which seems incredibly reasonable especially compared to many places in the city. Before I get carried away with this project, has anyone else already done this? Or are there any thoughts about especially good and well-priced wine lists, or the contrary? I haven't entered the data yet, but it seems that Commis and Wood Tavern are also good values (which is, I hasten to add, different than low-priced, at least for me).
