Rubbin' Butts sounds like it could get you what you need. Good food at pretty reasonable prices too. If you take a look at their menu you will see some options. Portions are large, for instance the Family 4 dinner easily serves about 8. They can also customize for your larger group, just give them a call. have a great gathering!
