The service has always been adequate. It hasn't ever been spectacular, but it has never been bad.
Being located in the casino, you would think it would be noisy. However, it is located in a separate room so the noise level wasn't bad. Nothing too fancy - it just feels like your average diner.
If you are visiting the El Capitan Casino, you might as well try out the diner while you are there. If you are a Hawthorne resident make sure to check out the Wednesday night buffet!
The El Capitan Diner is located inside the El Capitan Lodge & Casino in Hawthorne, Nevada. I have been to this diner several times because they run a lot of specials.
I usually order the breakfast special which comes with eggs, potatoes, and toast. I usually get the salad bar too which has a decent selection of toppings and dressings available. I also like the buffet which they hold on Wednesday nights.
