Love dining at Ichiza whenever I am in Las Vegas, and definitely love bringing my friends here if they are willing to venture off the strip. Ichiza is located on the 2nd Floor of a tiny strip mall near Chinatown (It is in the same plaza as Mian and Tea Station) There are times that they get busy in the weekends, but usually the wait time is not that bad. Based on the looks of the tables, menu and decorations, this restaurant must have been here for ages.
Menu is fairly simple to understand, most dishes are for tapas/sharing, and I would recommend getting 3-4 dishes per person dining. Prices are fairly reasonable. Average per person can be $25up based on your appetite or whether you order any alcohol with your meal. Be adventurous and order things that you have never tried before. You can always ask the waitress for recommendation or whether you have ordered enough or not.
Pay special attention to their daily special by the front door (in english), they do have special items that are not listed in the menu that is definitely worth trying. Highly recommended. To the best of my knowledge, they do not take reservation over the phone. Your wait time might be longer if you have a bigger party.
