When I read about their $10 all-you-can-eat promo a few weeks ago, I made plans to attend with a big group of friends. Sushi Mon isn't our favorite place and we figured the wait would be pretty long, but since they clearly advertised a no reservations policy we figured it would be worth it to go and wait; We were severely wrong.
When we arrived there were a few people gathered outside and the restaurant was full, but it wasn't too bad. When I went to the hostess to put our name on the list, we were informed they were booked solid until the end of their event and we couldn't be served even though our whole party was present. So much for the "no reservations" policy.
Save yourself the trouble, there's all-you-can-eat sushi places nearby with better flavor and similar prices--we won't be returning.
