From the Busch Stadium Information Guide: Guests may bring their own food & drinks into Busch Stadium for all games. Most food items are permitted, but guests should consider our bag policy when deciding what food to bring. Alcohol, bottles, cans, thermoses, hard-sided coolers, ice packs, and cups/mugs are not permitted. Non-alcoholic beverages including water and soda in factory sealed clear plastic containers no larger than 2 liters are allowed. Food & beverages from the outside will not be permitted in the Cardinals Club, Luxury Suites, Party Suites or any of our other All Inclusive Areas.
Just coming from the stadium, now. The first post is the most accurate. I always bring my own bottle of soda or water because I don't like Coke products. As mentioned in the first post, it must be factory sealed. Don't brake the seal until you are inside the ballpark. We also bring our own bag of snacks... Popcorn, peanuts, sandwiches. You may bring your own EMPTY cup into the stadium. Plastic, no metal cups, I asked about this yesterday at yesterdays game. Pocket knives under 4" inches are allowed. This is on the sign posted by the entrance. We go lots, if knowing that helps.
This year you can bring an empty cup. Bring a blanket if you want. Bring snacks in are fine. No drinks. Clear small purse...no backpacks at all.
And most importantly no guns or knifes. Pocket knives under a certain length can be permitted in. Best solutions is not to bring either!
Soft sided coolers and bags are limited to what fits under the seat. Not sure exact dimensions but about 10" tall, 16" long is a guess.
From what I understand you really can't bring it anything no food no drinks now from what I talked about with a friend he said you can bring like something to sit on to be more comfortable be sure not to have anything in your pockets that they might take away like a small pocket knife that kind of thing
