The waits are long because the hype is true. I've only been here once so have not tried too much on their menu, but everything i did experience was five stars.
Firstly... the food: The Bueno Beni was great. The eggs were perfectly done and the spiciness added with the salsa and fresh jalepenos was a great twist on your normal eggs beni. would certainly get this again. The wife got some sort of healthy omelette which seemed good, but she's a breakfast rookie and hence doesn't understand that the meal is all about maximizing grease, butter and hollandaise. But you can do that if it's your thing. Looked good.
Second... service: What you'd hope for for breakfast. Quick. Not in your face... more just to facilitate you getting in and out and keep your coffee and water full. We sat at the counter, which was a little cramped, but was the quickest way to get a seat. Overheard a couple next to us which sent back a meal for a reason that was completely not the fault of the server/restaurant, and he dealt with it very professionally... it reminded me of why i'm not cut out for food service.
Third.... price: very reasonable. You're far away enough from the strip that you dont have to deal with the whole 3,000% markup thing.
Highly recommend. For the money, it's one of the best breakfast spots in town.
