Baby shower help

Amanda

Hi sorry I don’t know where to post this so I figure I would just get the most responses here. I am trying to figure out a baby shower location. My sister is mainly hosting but I’m allowed to voice my ideas. My sister is on a budget and I don’t need or want her to pay for everything if possible. I’m happy to help where I can. Anyways I was thinking about having the party at a restaurant on a patio at one of our favorite Mexican restaurants but am I required to pay for everyone’s meals? Or can we just put on the invite purchase lunch on your own dime if you’re hungry? I wouldn’t word it that way I just want to know if that’s rude to ask people to pay for their own meal if they want to eat. Thanks everyone!
