Ha! First review. Really?
Blizz is IMNSHO the best place to have breakfast in MGM if you aren't one of those 'would rather eat massive amounts of crappy food from the trough' buffet types. For ten bucks plus tax you can get either crepes or waffles (made to order) with all sorts of fruity, nutella-ey, or savory toppings. And either a soda or a smoothie (extra charge of course).
They also have one of those make-your-own fro-yo bars with lots of flavors and toppings at 59c an oz.
I had "The Congo" nutella + banana crepes and they were pretty good. Not the best crepes I've had but decent compared to the crap at the food court and more interesting / less expensive than Studio Cafe. (Where all the breakfasts are about $15+)
I also visited Blizz for dessert one night during my trip and got a piece of chocolate molten lava cake for $4.95. It was pretty good too and they packaged it to go so I could have my chocolate orgy in private.
I think they open at 8am during the week, which sadly wasn't early enough several days of my visit but it was the most satisfying breakfast I had during the week.
