Since moving to AZ from LA a little over a year ago, I really struggled finding a really good Mexican spot and Mariscos, especially in the East Valley. I have yet to find a place in which the food reminds of home, so when I finally went to Senor Ozzy's, I was in heaven. It takes me 40-45 minutes to get there, but believe me it is really worth the drive.
First the prices are really good and they run specials all the time for example 10 tacos for $10. You can't compete with that at all.
They have marlin tacos that are so tasty and the mulitas are awesome. They have a pretty full menu, so any type of craving you may have, they will fill it.
The servers are very humble and accommodating and usually walk out in a food coma.
Also, don't forget to get a cup of their SenorChelada beer mix. That is also the best tasting michelada mix I have ever had. You can taste the fresh ingredients that they use in the mix.
