FOLLY: I honestly don't know much about private dining.
NOSA: There's this place called Hole In The Wall that I found on Instagram. Private dining is their thing. Never tried it so I can't recommend off personal experience or give you more details. You can give them a call and get more details.
Oh, Mansilla has a private dining area too, but I'm not too sure how many people it can take.
FOLLY: I noticed you put the great in caps and so the food is definitely important to you. Unfortunately, based on your requirement, I really doubt you'd get what you're looking for on the mainland. As Nosa says, every single picture at RSVP always bangs so that's an option if budget is not a constraint.
NOSA: I don't think I've ever encountered a buffet with "GREAT" good. You get decent food, but not great. Closest you'll get is that Sheraton in Ikeja.
FOLLY: We absolutely don't choose who gets to come, we send emails out every month with the deets. Also, it could be that you didn't confirm your subscription after you submitted your email. Okay no RSVP, if you like sushi you can try Izanagi.
NOSA: No budget? You have a lot of options then. You can try 1415 in Eko Signature or the new one, Crossroads. We've not tried Talindo but I've heard that's really good. Only reason we haven't tried it is because bank account no 'gree.
