The term "spicy," did not suggest to me a yearning for an anthroepicurean odyssey of gastronomic proportions. For that, I would suggest the similarly low priced Berta's in Old Town, with an eclectic mix of dishes from various South American countries. I believe the owners are Chilean. You can get spicy there, as well as a multitude of options for Mrs. Santa. If the search is for Mexican haught cuisine, I don't believe the restaurant will be promoted as "Mexican." My best guess in that regard, without actualy checking, would be Loew's.
