UPDATE: Tried the level 10 for 20 cents more. It is reallyyyyy good & tolerable even if you're not used to spicy food everyday.\n\n-----------------------------------\n\nJapanese Curry Zen is AMAZING. I usually come here after my classes since UNLV is sorta close to Chinatown, and I am always happy with the food and service I receive. The waiters/waitresses are always attentive and kind. I usually get the chicken katsu curry spice level 3. I think spice level 3 is the perfect amount of spicy and deliciousness. I have tried their curry with no spice level, and level 1 and it wasn't quite the same (although still delicious). Their takoyaki and katsu-don are pretty good, but their authentic Japanese curry is what makes this place 5 stars. \n\nIt shares the same plaza as Monta Ramen, Kung Fu Tea and SnowFlake Shavery (I recommend these places too) I hope one day they get another location for us people who live more on the south side of Vegas, like how Monta has a location on Eastern. I'd eat there more often!
