Is there any place in White Plains to get really good authentic Mexican food?

Lolla's just opened up next to Butterfield's and it is supposed to be outstanding. 147 Mamaroneck Ave, White Plains, NY

These are two places that have a good reputation, although I'm not sure about the authentic part of it!:
Mariachi Loco
394 Central Park Ave
White Plains, NY 10606
(914) 287-0001

Fresh Tortilla & Mexican Food (although they also have a Chinese menu!)
70 Mamaroneck Ave
White Plains, NY 10601
(914) 428-5428

I have heard that Coyote Flaco in nearby Port Chester is one of the most authentic Mexican restaurants.
