I really enjoy going to the Peppermill because of it's all-in-one casino / hotel. Although they are not located near the casino / hotels in downtown Reno, you will find that the Peppermill has everything you're looking for in one place.
As soon as you step in the casino, you will see an amazing number of colorful lights and you have to try-out their chairs in the casino! Nicely cushioned with arm-rests that swivel (unlike other places where you have to push and pull the chair to make it stay in a certain position).
My favorite place to eat at the Peppermill is the 24-hour Coffee Shop. Some of the items I've enjoyed are the Buffalo Chicken Salad, Mongolian Beef and for dessert...Mud Pie -- best Mud Pie I ever had!
If you have a big appetite, check out their Island Buffet. I love how it makes me feel like I'm in a rainforest by having sounds of rain and birds chirping.
If you're looking for more of a fine dining and / or romantic experience, I would recommend the Romanza. I had the Fettuccine Carbonara which was exquisite!
