E3 Steakhouse could possibly work. I can connect you with their catering/event person and she can help you out and confirm (or not) exactly what you are looking for. I think you have been there before. Not sure whether you liked it or not. Walking distance from the Park.
Thanks! Yeah I've been there. The reason I want walk in and not reservation is because if I have to organize a dinner I'm not doing this. Fogo was great. I tell them I got an unknown headcount, and they said, that's cool, come on in. If I gotta organize, sell tickets, etc, fuck that. 😂
