Wow, are all restaurants in Phoenix closed on Monday evenings? After getting denied from Los Sombreros, my friend and I stumbled upon Havana Cafe. We both ordered chicken dishes: mine with onions, peppers and rice, her's in a big metal pot. Both were generously portions (her's especially came with almost a whole chicken), reasonably tasty, but nothing special. The tres leches dessert was pretty good, but also nothing to write home about.
They have really cheap Margarita Monday specials!
