Burger Supreme

The great equalizer: Burger Supreme. Everyone from Provo probably knows it, and for me it was a favorite and the first of these Greek burger places that I was really familiar with. So, how does it stack up?

Pastrami Burger: 8
Tomato, lettuce like the normal toppings, but with a tiny bit of (what I think is) the fry sauce and a slice of american cheese. The truth is that the american cheese doesn't go as well with the burger as the swiss did at Mad Greek, and it's almost too much.
The killer of this burger, though, is the pastrami. It's a subtle difference, such that it took me a minute to realize what it is, but the pastrami on this burger takes more like corned beef than normal pastrami, so it has a really unique flavor that I think makes the burger.
(And as a side note, I looked up pastrami and corned beef, and they're almost the same meat, except that pastrami is smoked and peppered. So, maybe BS just doesn't smoke their pastrami, and that's how they get the unique hybrid flavor. That's just a theory, of course.)
I think this is still the best pastrami burger I've had. If it had swiss instead of american cheese, it might be unbeatable.

Gyro: 8
The first thing I noticed about the gyro at BS is just how juicy the meat is. The slices are thick, juicy, and flavorful. Can I say juicy one more time? The meat was great.
The cucumber sauce was creamy, but not with the same extraordinary richness that Mad Greek had. It was, however, full of chopped cucumber, onion and tomato. The cucumber really added a freshness to it.
The oil, however, was a noticeable downside. While Mad Greek's oil has a unique and pleasant flavor, Burger Supreme's seems like normal animal/vegetable fat, so the presence of the oil kind of weighs the gyro down and makes it seem heavier and greasier than it needs to be.

French Fries: 7
The fries are very greasy at BS, but not so much that it makes them soft or soggy. On the contrary, they were fresh and very crispy, which in my opinion, makes them great. (And from experience from visiting this place many times when I lived in Provo, I can say that they're consistently this way.)

Fry Sauce: 7
The fry sauce is ketchup and mayo, like usual (and I don't think it's any weird kind of mayo). It does have a little bit higher content of mayo than ketchup (which I like, but I realize that not everyone does).

Conclusion
The thing Burger Supreme does best is meat. The meats are flavorful and juicy. (I know I've said that too much, but it really is true.) While the trimmings (like sauces and cheeses) are consistently good, they're not anything extraordinary, either.
