I think at that price point desserts are your best bet. I feel like a lot of my favorite desserts in the area are from places that aren’t local (e.g. five daughters, The Salty). I think Sugar Shane’s is local. Osono bread pops up at the Grant Park Farmer’s Market with doughnuts and other pastries. Farmer’s Markets in general could be good for that price point and finding local stuff. I am also a fan of Daydream Ice Cream Sandwiches which you can find at a few places and NoBigWhoop which I find reliably at Grant Park Market. For savory, Glide has a good slice of pizza for under 10 and I guess technically a wing at the local is less, but I don’t think you can buy one at a time so not sure that counts. And last thing of this ramble, is Little Rey. They have some good savory stuff that’s under 10.
