I went last night and it was dismal, even the "fresh home made" salsa was bland and tasted just like something from a cheap supermarket. ALso, the menu was pretty much exactly Tex Mex. Oh well, back to California for proper Mexican food I guess. www.andyhayler.com has a detailed review if you like to observe suffering
