I have a Large BGE and a family of 5. Just off the top of my head, I'd say:

You can make enough pulled pork on a Large to feed a big crowd all in once. 20-30 people is not a
problem at all and you can go bigger if needed. Other recipes for big meals - brisket, pot of stew,
roast, turkey, etc. All would be good choices for big family gatherings.

On the other hand, pizzas cook one at a time and take 10-15 minutes each. You can't have
several ready at once all hot off the grill. Not a good choice if you're trying to feed a pack
of hungry kids.

A large will easily cook enough burgers, reasonable sized steaks, or chicken breasts for 8-10
people.

Ribs take up a lot of room. Tough to cook those for a crowd. My experience is that feeding 4-6
adults is about the limit for cooking on a single level with the rib rack I'm using. If you
need more than that, you will have to get creative with grid extenders, etc.

Hello Steve,

If there is an Eggfest near you you can pick up a large BGE (demo) with several accessories for
around 650.00 I recently purchased one to pick up in a few daysc at The Pacific Northwest Eggfest.

Good Luck!

I'm in St. Louis and that's the best price I found here. Most were higher with nest &
shelves.

As far as how many you can cook for, I've cooked pulled pork for 25-30 people, ribs for a dozen
and lots of stuff for just my family of four. I Don't regret not going bigger or smaller. The
large is perfect for us.
