It's Great Lake (singular) Pizza.
I've been hesitant to post about this stellar pizza mostly because of the challenging business model they've set up of having little table space available to accommodate its patrons. Trix gave up trying after her third or fourth attempt even though I insisted it was worth pursuing.
Pizza-wise, though, no one can touch them in Chicago. Their wonderfully airy and tasty bread, cooked to perfection, is in a league all its own for Chicago (or virtually anywhere, for that matter). Their high-quality toppings (such as Newsom's country ham, for example) are in total harmony and proper proportion with the entire pie; a rarity even at the highest echelons of the pizza world.
Last Saturday, I ran into the owner at the Green City market at 7:30am where she was procuring her ultra-fresh local produce. She informed me that Great Lake plans sometime soon to extend their hours (opening up the first and third Tuesdays of the month and extending the normal daily hours from 9pm to 10pm.
One of my ultimate night's out in Chicago starts with a cocktail at In Fine Spirits with one of the best bartenders in town (Benjamin, a true professional bartender in every sense of the word), followed by a short walk around the corner to Great Lake Pizza, and then finishing with the marvel desserts on offer at Pasticceria Natalina. For me, it doesn't get any better than this.
This is truly special pizza; bad business model or not.
