Slyman's is one of Cleveland's most beloved hot spots and for a dang good reason. It's one of those places that doesn't dabble in anything that they can't blow out of the park. It's no lie that Slyman's has the best Corned Beef on the planet - simply because the beef is the star. There are no shenanigans going on in your sandwich. It's just a mass of mouth watering, high-blood-pressure-inducing corned beef on rye bread. Although the rye is also pretty good, it doesn't really matter because the meat is what people come for. And believe me, the people flock in masses. Don't plan on making it a quick in-and-out run because there is always a line out the door - a good sign for any restaurant. The staff are no-nonsense type of people but they are helpful and work hard to get you tasting their meat as soon as humanly possible.
I also have to give major props on the thousand island dressing they use which is some of the best I've had. I could drink the stuff it is so good. While everything I've tried is great, the Reuben is my favorite.
Don't be too shocked by the slightly hefty prices as you will be eating enough food to satiate a small village. You could probably make this meal last for 3 lunches if you wanted to... which you won't because it is just that good.
My only real complaint is that the hours are terrible. They close at 2 pm most days so if you were wanting some corned beef for dinner, you better plan on buying by the pound at lunchtime (which you fortunately can do).
