Cream City veneer can be hard to come by, or hard to find. You might have better luck finding actual Cream City brick. Still might be a bit difficult or pricey. It is some lovely stuff though, I got a small stack of it that was salvaged. Chicago might be easier to find, though I know it's not the same as Cream City.

But brick veneer can be found and can be fairly easy to DIY. Stuff comes in tiles and panels. There's companies that specialize in it, or you can even find it in the big box stores.

How difficult of an install you will have will depend a bit on what you already have. What are your walls currently?

I have concrete brick walls. Now they are bare stud walls... So at this point pictures would do nothing. My vision would be the faux brick behind the bar (stained gray cabinets) and then utilize black for art work on walls and matte black ceiling. Going for industrial feel... I would like a Milwaukee feel/theme for it. the slimbrick looks really good, but colors are not quite right.

Maybe you need to alter the colors you want for the rest of the space to go with the brick you can find. I hope you have added a ton of lighting black ceilings gobble light like crazy.

There is thin brick veneer that you can apply to your walls, but I'm not sure it will match the color you're after.

If you are at studs, then you are at a good blank to start with. Brick tile isn't that much different than other tiles. Make sure you set up your walls very plumb and smooth- this will help make your finished walls even and nice.

I would skip the matte black for the ceiling. Go for someting in the steel family of metallics. Matte black is a different kind of club look than industrial unless your got some seriously high ceilings gong on. Since it's a basement I'm going to guess you don't. So, metallics in the steel family, perhaps even hits of copper or brass to help give nod to the brewery aspect out of Milwaulkee. It would work better with the Cream City brick. The black art and gray cabinets can work, just make sure you keep the grey to the metals family side and don't get all crazy huge with the art. You can complement and work in more industrial with metal pipes for some of your detailing.

What do you have for pipes? As in plumbing, is this going to be a wet bar? What's your electric set up for lighting, a fridge, ice? And if you plan on gatherings, having some sort of ventilation or exaust fan because sometimes that's nice.
