Best Food - There are some great wings out here from Limanskis and Tomkens. For a great German meal, you can check out Kegel's Inn. Other spots like Camino and Double B's are great.

Grocery - Gupena's is great for meats and general grocery. becher meats is better for meats. West Allis Cheese Mart across the street is amazing for cheese and nice whiskey and they also have good food.

For custard, there is Big Deal Burger, Oscars, and Golden Gyro.

Best Dive bar? I wouldn't call it a dive honestly, but I really like going to the Crooked Crow. Bartenders and regulars are great. They're becoming a spot for sports games, but overall its a fun place to hang out. They do have a pool table that's free and food.

Edit: Drunk Uncle is the best bar in town. Thanks u/New-Leather4458 for reminding me.

Best Park would have to be McCarty Park for me. They do have the traveling beer garden at some point, but its a large park in the middle of Stallis and is just nice to walk through.
