I have avoided Mexi-Sushi places in the past due to my snobbish sushi attitude. However, now that I have an amazing Latina in my life, she has opened my eyes to this interesting fusion.
We tried Extreme Sushi today and were pleasantly surprised at the food quality, vast portions and friendly service. It does help to speak Spanish so we had no trouble ordering.
We tried a baked roll, a deep fried roll and a "natural" roll (can't remember the name but it had pulpo inside) today. While the prices are a bit more than you'd pay at a standard Japanese Sushi establishment, the portion sizes here are HUGE. Even the ginger comes in a larger bowl than usual.
Eel sauce and spicy mayo sauce also in abundance at the table side...and limes!! Yes it's delicious on sushi!
Of note -- most of the rolls have cream cheese inside. Apparently Mexi-sushi is known for the use of cream cheese so if you're not a cream cheese fan, you'll be hard pressed to find a roll on the menu w/out it.
All-in-all the experience was very good. My gf commented that it was close in quality and flavor to her favorite Mexi-Sushi place in Mexicali. There is a fresh seafood store right next door so I'm deducting that Extreme uses fresh seafood/fish.
