Can people from the same group buy food from different restaurants and eat at a table all together? Or do you have to eat wherever you bought your food?

There's an open area, an Aile way, you can gather there.

If you request a to-go I don't see y you can't all sit together inside or outside

There are various areas to sit inside. But the patio outdoor seating is more for individual shops. You enter and exit through the store.

Yes most definitely place inside and outside I believe weather permitted!! That place Rocks!! Definitely go back again :)
