We have a group of 20 people but we all are not on one check we have about 5 or 6 seperate checks for saturday at 630 can we do that

I'd get reservations and tell the server upfront who pays for what so everyone will automatically get their separate bill

Absolutely. They are very accommodating.

Ues you can.however on the weekends i would make reservations.last time i went on sat night it was a 2hr wait
