Its a combination food mart, sit-in cafe, and takeout place open for most of the day. If you're staying at Vdara, probably the most convenient option. I ordered breakfast here to take back to the room. Wait time was over 15 minutes, though they didn't seem all that busy.
I ordered a 3-egg omelet for the wife with crab meat and provolone. It was pretty good - they used real and not imitation crab. A dash of tabasco went well here. The omelet came with roasted potatoes and your choice of toast. I got the pancakes which were three large ones with strawberry preserves on the side. Though they have a banana foster option - it was just a cup of sliced bananas and no ice cream or caramel or rum sauce : (. Pancakes themselves were on the dry side and just mediocre.
I do think they have a decent menu and the place looks clean and well stocked.
