Once you get off the Strip, Las Vegas truly is full of great restaurants that offer great value. Basically, unless you're truly a lazy jackass, you can definitely escape the price gouging that happens on the Strip.
Case in point, Sakana. I'm not really much of an AYCE guys these days. But we were absolutely starving and the AYCE is worth it if you order three rolls. Fish was pretty fresh for Vegas standards and you could definitely taste the quality in the rolls. On top of that, I loved how almost everything (including nigiri!) was on the table for AYCE. And those cuts of fish are huge for nigiri! They definitely don't jip you on it.
Of course, with any AYCE place...you'd be best to just order everything upfront in the first round of orders. Service does typically get slow after that. Overall though, service was solid enough and I have no complaints.
Definitely glad I found this little gem and will come back for sure!
