Small, privately owned Japanese market.
I was craving Yoshinoya (beef bowl/teriyaki chicken bowl) but there are no branches out here. I didn't feel like going to a sit down restaurant but I was craving Japanese food so I came here to check out their premade food. I bought some premade beef and teriyaki chicken bowls which ended up being quite tasty and great for pack lunches. I also got a katsu bento and spicy tuna sushi. I liked the fact that it kind of had a "home made" aspect to it. I could be imaging it though! Lastly, The prices were more than fair for the taste and quality.
EDIT: There is a Yoshinoya in Vegas on Maryland Parkway just north of Tropicana (Thanks Lisa!)
