I went there last night (5th Ave and 46th St), never having been there before, at about 9 pm. The stand was closed up but there was a restaurant just around the corner that is called La Guera (with an umlaut over the the u) which said "Rico's Tamales" on a sandwich board in front of it. What's going on? Anyway, I got two tamales there, one with mole and one with salsa verde (they were out of the chicken with red sauce). The mole tamale was a little bit rich and messy but palatable, and the salsa verde tamale was pleasantly spicy. I also got two tacos, one with carnitas and one al pastor, which were alright, not much of a standout on the 5th Avenue strip.
If these weren't the real Rico's things, I still want to try Rico's, so I'm wondering if anyone knowns what the deal is. I happened to catch a glimpse of the food safety license-thing and it was dated May 31 so this may be a pretty new development for the Rico's folk.
