Love, love, love this place! The food is always excellent and the portions are enormous. I want to say their omelets have like 6 eggs in them (or more). Seriously, come hungry or be prepared to take home leftovers.
When a place is 24 hours and they serve breakfast the whole time, I tend toward breakfast food. That being said, their eggs benedict is one of the best in Las Vegas. Burgers are delish and cooked to order (beware asking for rare...they take it seriously and will produce something pretty much raw on the inside). The service is great. Waitresses are attentive and friendly. There seem to always be cops eating there; take what you will from that.
Downsides: The place gets crowded. Really crowded. Weeknights seem to be the best time to go if you want to sit down and eat quickly. Also, the parking situation can be difficult. They have an itty bitty parking lot in front (maybe more in the back, not sure!) right on LV Blvd, so getting out can be tricky.
Bottom line: if you haven't been, go for the decor. Stay for the food!
