Last Thursday members of my city Bdx group welcomed back Matt, one of founders. We ate at Rothmans, they gave us no corkage deal. I think we opened all of the bottles except the sticky, and did all the pouring. They were good about giving us stems (3 per person, and some asked for 4th) and we had good service. They also brought out little dessert glasses for the Vouvray Moelleux, don't think anyone used. Bill was roughly $725, since no corkage we figured 30% tip. Easier just to round up to $110 per person, which I guess works out to about 35%. No one objected. My part of the tip was less than $30. If we had tipped 20%, it would have been $16+. I'd rather spend an extra 13-14 bucks and be pretty certain that waitstaff is happy and that we are likely to be welcomed back. I'd guess the retail value of the wine we drank was at least $2,500,so if on a NYC list at least $5K, so seems like quibbling over $14 is a bit crazy.
