I like Taco Taco on the UES so I was happy when Mole opened downtown. I called early in the week because I wanted to do a dinner for a group of 10 people at 8 PM on a Friday night. They don't take reservations normally, but for a big group they will do a sort of prix fixe menu and give you a reservation. When we arrived, the table was all set. We brought beer, wine, and tequila; they mixed margaritas for us with their own mix, cut up limes, gave us wine glasses, etc. The menu, for $25 a person, was really generous: tons of fabulous guacamole mixed right at the table, with chips; appetizers; and big platters of tons of different kinds of meats, with corn tortillas, rice, and refried beans. They kept the birthday cake I brought in the fridge until dessert. The waiters were great and didn't rush us at all, and we had a really wonderful night!
Pros: Ability to seat a large group with advance notice, BYOB!
