I there a place open around lunch time which has a private room or section that can be reserved for approx 30 people after a service?

I can understand the rules of the cemetary about flowers,trinkets,etc. But I dont understand why a simple American Flag can't be left next to a stone all the time? Any answers?

There are a few locations at 441 and lantana just north of Target that may be able to accommodate your needs

There are a few restaurants on Boyton Beach road, between 441 & the turnpike that can probably handle that for you.
