This party ended with the kids having a snack outside the Build A Bear store in the middle of the mall walkway! They so don’t care. And if it’s a mall that has tables around, you can just move a few in front of the store. Now depending on your mall, you MIGHT have to talk with them and let them know what you are doing. But I don’t think it would be a problem. People are eating out in the mall hallways all the time.
There are several positive aspects about this. You have control over the food and cake. Often when you go to certain party places, they require that you use their food and cake. Not the case here! And it’s indoors. So, no matter what time of year it will be warm and dry. Always a plus. I had a party for my son last year that was FREEZING in May and it was outside. Disaster.
Anyway, even though you are thinking of having a party at a particular store in a mall, don’t let that box you in. No matter if it’s Build A Bear or some other store, think outside the store and use your surroundings.
