Authentic and Tasty Mexican in Bellevue.
Funky older place in downtown Bellevue, Las Margaritas is super authentic, and great place for either happy hour, and hungover dinner especial, or a place to bring kids (it's pretty mellow)...
Stick with Azteca.
I definately will not be coming back to the Bellevue Las Margaritas. I ordered the vegetable enchaladas (which I get at another restuant) and ended up with a plate, I am not joking, of velveta covered corn tortillas with that god aweful frozen vegetable confetti. I felt like I was being handed baby food. On top of that the mexican rice was bland and the beans were terrible. I couldn't even force it down.
I'm not sure if I've ever been to the one in Bellevue, but the one in Issaquah is GREAT! Almost like a hole in the wall place, but their pico de gallo, is fantastic! Once I found Las Margaritas, I haven't gone back to Azteca since.
