But I just got off the phone with Ribs & Rump. Unfortunately due to our large number and on a weekend, they are only able to accommodate us up to 8 PM.

This is a very tight time frame on ordering dinner and finishing. I asked if we could reduce still keep a smaller number of tables after 8, but they said they re-book the tables and will kick everyone out. So do we stick with this venue, in which case everyone who's a maybe best confirm yes or no, and everyone needs to be on time for dinner or eat beforehand and join us afterwards. Or do we go elsewhere?
If worse comes to worst, anyone who misses dinner at R&R can eat at the brewery/bar & grill 100 metres down the block and then join the group afterwards.
