Re: Question about food in the stadium
No glass bottles or cans may be brought into Great American Ball Park. Guests are welcome to bring in soft drinks and water provided they are in clear plastic bottles and the safety seal has not been broken. Insulated foam cups/containers from restaurants, convenience stores or gas stations, etc. are not permitted in Great American Ball Park.
I've seen families with pretty complete picnic lunches in there. Sandwiches, baggies of pretzels, snack packs. Don't know how much "sneaking" past security was involved.
When all is said and done more is said than done.
