Your best advice for the south loop please!

Would love some recs for best beef, pizza, Chinatown grub in the area, yet willing to take the train if we need to, plus maybe a good bakery/donut shop to walk to. I’m heading that way next week, family trip doing museums and shedd but I want all the info for spots I can’t miss while I’m there! But need to stay kinda budget. Also taking the water taxi from Chinatown to michigan one day so any random wild card options would be an awesome bonus!!!!! Thanks

Also, deep dish pizza is NOT a requirement ✌️
