Sushi Mon always has the best when it comes to all you can eat sushi. Sure, it's not as good as the top tier a la carte restaurants, but it's nice to enjoy flavorful, quality, all you can eat when you are feeling a little gluttonous.
The service is hit or miss, especially when they are busier, but if you sit at the counter and buy your chef a beer, you'll be taken care of like a VIP all night.
