This is my favorite sushi place in the world. The first time I was there they had Toro on the all u can eat, and they still do every once in a while...Toros is $12 an order usually! Hell of a deal.
Now the problem with most all you can swallow sushi places is that every roll is on top of a cali roll, the lamest roll ever. Sushi Mon is not that way! I recommend you get a Sunrise, Jala Jala, JJ, Moon, and the sweet shrip upon sitting down. Also the sweet shrimp heads! DELICIOUS!!!!
Also if you like Ponzu sauce, and if don't I hope you have nightmares, you'll love the Albacore, Garlic Tuna, and Yellowtail Collar. That right there should be enough for ya.
Realize also get your Miso soup (if don't finish it you can hid rice in it...shhhh!) And some steamed gyoza. Because you have too!
