Moon Palace in Chinatown. We went after I was sworn into the Bar. I do have a history of choosing places like this. When I graduated from Graduate school we did Cafe Bolero. It was the weekend so many in the party had the Paella. When I graduated from undergrad (ages ago) we did Cross Rhodes in Evanston and Ofame (now gone, unfortunately) in Lincoln Park.
What kind of food do you like? Are there any folks who are not terribly adventerous in your party (relatives from a small town who have no idea what natto is

) What about folks with special needs like wheel chair access?
