Can Dave and Buster's accommodate 25-30 people along with giving out separate checks?

I would say that, based on my experience, they will bend over backwards to accommodate customers.

I'm not sure they giving out 30 checks but can accommodate 30 easily, most places will work around 7-8 checks, Venmo and Spliwsie are really useful for groups to square finances fairly and evenly and do more complex payments
