Sushi Mon - 2 Locations?
The Sushi Mon on Sahara is NOT related to the Sushi Mon in Henderson. The Sushi Mon in Henderson, in my opinion, is far superior. However, if you are on the west side, then try Sushi House Goyemon, which IS related to the Sushi Mon in Henderson. Sushi House Goyemon also offers some menu items not available at Sushi Mon in Henderson, like grilled pork belly, crispy rice tuna, and ramen (ramen only after 10 or 11pm). These "extra" menu items are included in the AYCE price. Goyemon also has a superior sake list, as well. Goyemon and Sushi Mon Henderson also use the same punch card, so your punches from both locations count towards your freebie.
Also, for what it's worth, Sushi House Goyemon and Sushi Mon in Henderson are also both related to Monta Ramen.
