Augustus Cafe is like the homely, old high school friend that's always willing to hang out. If you're staying at Caesars Palace, it's always open and even during slow times, the Cafe still gets moderate traffic.
The problem with ol' Augustus is that I have never had a great time with him. He's comfortable, that much is true, because I know him well. They serve pretty much your standard American fare with a few random outliers (most of which are Italian).
Augustus is really no fun. Be willing to wait in line here. I had the Caesars VIP pass that let me cut in front of all the sad folks who have been standing in line for a good 45 minutes. I truly did feel bad for these people but, hey, Augustus and I go way back.
The service here is fair at best. It gets insanely busy in the restaurant. I'm not looking to constantly hold hands with the server but throw me a bone here. At least think to refill my water before I struggle to wave you over for 10 minutes.
The only redeeming factor is that Augustus is there for you when you need him and he's surprisingly dapper in the morning. I will say that the one thing that Augustus does well is breakfast. If you can beat the breakfast rush, they have some pretty high-quality items going on.
If you've got another option, take it, otherwise prepare for a meal version of watching the Lord of the Rings trilogy.
