I had lunch today at Lupita's, which is in what I think is called the Iron Horse Center (could be wrong there) but is at the Northwest Corner of Prater and McCarran. There was a bar there before, I think (far end of the shopping center, closest to McCarran).
Anyway, they have excellent seafood dishes. The Ceviche was great! Also good sopes and tacos...and camarones rancheros. You can get a combination with two items, excellent rice and beans(didn't try the beans, too full!) for $4.95..individual tacos are 0.85 with plenty of meat and two small tortillas, cilantro and onion...you know, the usual taqueria fare. You can get a cevice tostada with a decent amount of ceviche for a ridiculously low price. I think the highest item on the menu is 7.95. The place advertises homemade tortillas, and they taste homemade (wonderful!). I just hope it lasts, especially at those prices!
(This is across the street from BJs BarBQue at the Northeast corner of Prater and McCarran, so if any of you out-of-towner chowhounds make your way to Sparks, check out this corner. Good food; good prices.)
